elisp/contrib/evil-surround/README.md

+This package emulates [surround.vim by Tim Pope](https://github.com/tpope/vim-surround).
+The functionality is wrapped into a minor mode.
+To enable it globally, add the following lines to ~/.emacs:
+
+    (require 'surround)
+    (global-surround-mode 1)
+
+Alternatively, you can enable surround-mode along a major mode by adding
+`turn-on-surround-mode' to the mode hook.
+
+This package uses [Evil](surround.vim by Tim Pope) as its vi layer.
+
+## Add surrounding ##
+You can surround in visual-state with `s<textobject><trigger>`
+or in normal-state with `ys<textobject><trigger>`.
+
+## Change surrounding ##
+You can change a surrounding with `cs<old-trigger><new-trigger>`.
+
+## Delete surrounding ##
+You can delete a surrounding with `cd<old-trigger><new-trigger>`.
+
+## Add new surround pairs ##
+A surround pair is this (trigger char with textual left and right strings):
+
+    (?> . ("<" . ">"))
+
+or this (trigger char and calling a function):
+
+    (?< . surround-read-tag)
+
+You can add new by adding them to `surround-pairs-alist`.
+For more information do: `C-h v surround-pairs-alist`.
+
+`surround-pairs-alist` is a buffer local variable, which means that you can have
+different surround pairs in different modes.
+By default `<` is used to insert a tag, in C++ this may not be useful - but
+inserting angle brackets is, so you can add this:
+
+    (add-hook 'c++-mode-hook (lambda ()
+                               (push '(?< . ("< " . " >")) surround-pairs-alist)))
+
+Don't worry about having two entries for `<` surround will take the first.
+
+Or in Emacs Lisp modes using \` to enter \` ' is quite useful, but not adding a
+pair of ` (the default behavior if no entry in `surround-pairs-alist` is
+present), so you can do this:
+
+    (add-hook 'emacs-lisp-mode-hook (lambda ()
+                                      (push '(?` . ("`" . "'")) surround-pairs-alist)))
+
+without affecting your Markdown surround pairs, where the default is useful.
+
+To change the default `surround-pairs-alist` you have to use `setq-default`, for
+example to remove all default pairs:
+
+    (setq-default surround-pairs-alist '())
+
+or to add a pair that surrounds with two ` if you enter ~:
+
+    (setq-default surround-pairs-alist (cons '(?~ ("``" . "``"))
+                                             surround-pairs-alist))
+
+## Usage examples ##
+
+Here are some usage examples (taken from
+[surround.vim](https://github.com/tpope/vim-surround/blob/master/README.markdown)):
+
+Press `cs"'` inside
+
+    "Hello world!"
+
+to change it to
+
+    'Hello world!'
+
+Now press `cs'<q>` to change it to
+
+    <q>Hello world!</q>
+
+To go full circle, press `cst"` to get
+
+    "Hello world!"
+
+To remove the delimiters entirely, press `ds"`.
+
+    Hello world!
+
+Now with the cursor on "Hello", press `ysiw]` (`iw` is a text object).
+
+    [Hello] world!
+
+Let's make that braces and add some space (use `}` instead of `{` for no
+space): `cs]{`
+
+    { Hello } world!
+
+Now wrap the entire line in parentheses with `yssb` or `yss)` (wrapping the line
+is currently broken see [issue #5](https://github.com/timcharper/evil-surround/issues/5)).
+
+    ({ Hello } world!)
+
+Revert to the original text: `ds{ds)`
+
+    Hello world!
+
+Emphasize hello: `ysiw<em>`
+
+    <em>Hello</em> world!
+
+Finally, let's try out visual mode. Press a capital V (for linewise
+visual mode) followed by `S<p class="important">`.
+
+    <p class="important">
+      <em>Hello</em> world!
+    </p>

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+@chapter Overview
+
+Evil is an extensible vi layer for Emacs.  It emulates the main features
+of Vim,@footnote{Vim is the most popular version of @dfn{vi}, a modal
+text editor with many implementations.  Vim also adds some functions of
+its own, like Visual selection and text objects.  For more information,
+see: @uref{http://www.vim.org/}} turning Emacs into a modal editor.
+Like Emacs in general, Evil is extensible in Emacs Lisp.

+@node Installation
+@section Installation
+
+Evil lives in a Git repository.  To download Evil, do:
+
+@example
+git clone git://gitorious.org/evil/evil.git
+@end example
+
+@noindent Move Evil to @code{~/.emacs.d/evil}.  Then add the following
+lines to @code{~/.emacs}:
+
+@lisp
+(add-to-list 'load-path "~/.emacs.d/evil")
+(require 'evil)
+(evil-mode 1)
+@end lisp
+
+@noindent Evil requires @code{undo-tree.el} to provide linear undo
+and undo branches.  It is available from
+EmacsWiki.@footnote{@uref{http://www.emacswiki.org/emacs/UndoTree}}
+(A copy of @code{undo-tree.el} is also included in the Git repository.)
+
+@node Modes and states
+@section Modes and states
+
+The next time Emacs is started, it will come up in @dfn{Normal state},
+denoted by @code{<N>} on the mode line.  This is where the main vi
+bindings are defined.  Note that you can always disable Normal state
+with @kbd{C-z}, which switches to an ``Emacs state'' (denoted by
+@code{<E>}) in which vi keys are completely disabled.  Press @kbd{C-z}
+again to switch back to Normal state.
+
+Evil uses the term @dfn{state} for what is called a ``mode'' in vi,
+since ``mode'' already has its own meaning in Emacs.  Evil defines a
+number of states, such as Normal state (@code{<N>}), Insert state
+(@code{<I>}), Visual state (@code{<V>}), Replace state (@code{<R>}),
+Operator-Pending state (@code{<O>}), Motion state (@code{<M>}) and Emacs
+state (@code{<E>}).  Each state has its own keymaps and customization
+variables.
+
+Meanwhile, a @dfn{mode} in Emacs is a set of key bindings for editing a
+certain sort of text, like @code{emacs-lisp-mode} for Emacs Lisp.  Modes
+may include custom bindings for Evil states.
+
+@node Settings
+@chapter Settings
+
+Evil's behavior can be adjusted by setting various variables.
+The current values may be inspected by doing
+@kbd{M-x customize-group RET evil RET}.
+
+To change the value of a variable, add a @samp{setq} form to
+@code{~/.emacs}, preferably before Evil is loaded:@footnote{Strictly
+speaking, the order only matters if the variable affects the way Evil is
+loaded.  This is the case with some of the @samp{evil-want-} variables.}
+
+@lisp
+(setq evil-shift-width 8)
+;; @r{Load Evil}
+(require 'evil) @r{@dots{}}
+@end lisp
+
+@noindent Note that if a variable is buffer-local, you must use
+@samp{setq-default} instead of @samp{setq} to change its global value.
+
+@defvar evil-auto-indent
+Whether the current line is indented when entering Insert state.
+If @code{t} (the default), then the line is indented.  If @code{nil},
+then the line is not indented.  Buffer-local.
+@end defvar
+
+@defvar evil-shift-width
+The number of columns a line is shifted by the commands
+@kbd{>} and @kbd{<}.
+@end defvar
+
+@defvar evil-repeat-move-cursor
+If @code{t} (the default), then repeating a command with @kbd{.} may
+change the position of the cursor.  If @code{nil}, then the original
+position is preserved.
+@end defvar
+
+@defvar evil-find-skip-newlines
+If @code{t}, then @kbd{f}, @kbd{F}, @kbd{t} and @kbd{T} may skip over
+newlines to find a character.  If @code{nil} (the default), then they
+are restricted to the current line.
+@end defvar
+
+@defvar evil-move-cursor-back
+If @code{t} (the default), then the cursor moves backwards when exiting
+Insert state.  If @code{nil}, then the cursor does not move.
+@end defvar
+
+@defvar evil-want-fine-undo
+If @code{t}, then a change-based action like @kbd{cw} may be undone
+in several steps.  If @code{nil} (the default), then it is undone in
+one step.
+@end defvar
+
+@defvar evil-regexp-search
+If @code{t} (the default), then @kbd{/} and @kbd{?} use regular
+expressions for searching.  If @code{nil}, they use plain text.
+@end defvar
+
+@defvar evil-search-wrap
+If @code{t} (the default), then @kbd{/} and @kbd{?} wrap the search
+around the buffer.  If @code{nil}, then they stop at buffer boundaries.
+@end defvar
+
+@defvar evil-flash-delay
+The number of seconds to flash search matches when pressing @kbd{n}
+and @kbd{N}.
+@end defvar
+
+@defvar evil-want-C-i-jump
+If @code{t} (the default), then @kbd{C-i} jumps forwards in the jump
+list.  If @code{nil}, then @kbd{C-i} inserts a tab.
+@end defvar
+
+@defvar evil-want-C-u-scroll
+If @code{t}, then @kbd{C-u} scrolls the buffer.  If @code{nil} (the
+default), then @kbd{C-u} begins a numeric prefix argument.

+
+@node The cursor
+@section The cursor
+
+A state may change the cursor's appearance.  The cursor settings are
+stored in the variables below, which may contain a cursor type as per
+the @samp{cursor-type} variable, a color string as passed to the
+@samp{set-cursor-color} function, a zero-argument function for changing
+the cursor, or a list of the above.  For example, the following changes
+the cursor in Replace state to a red box:
+
+@lisp
+(setq evil-replace-state-cursor '("red" box))
+@end lisp
+
+@noindent If the state does not specify a cursor,
+@samp{evil-default-cursor} is used.
+
+@defvar evil-default-cursor
+The default cursor.
+@end defvar
+
+@defvar evil-normal-state-cursor
+The cursor for Normal state.

+
+@defvar evil-emacs-state-cursor
+The cursor for Emacs state.
+@end defvar
+
+@node The initial state
+@section The initial state
+
+By default, a new buffer comes up in Normal state.  This can be changed
+with the function @samp{evil-set-initial-state}.
+
+@defun evil-set-initial-state mode state
+Set the initial state for a buffer in which @var{mode} is active to
+@var{state}.  @var{mode} should be a major mode such as
+@code{text-mode}, although minor modes work as well.
+@end defun
+
+@node Keymaps
+@chapter Keymaps
+
+Evil's key bindings are stored in a number of keymaps.  Each state has a
+@dfn{global keymap}, where the default key bindings for the state are
+stored.  For example, the global keymap for Normal state is
+@samp{evil-normal-state-map}, and the key bindings in this map are seen
+in all buffers that are currently in Normal state.
+
+Keymaps are modified with the Emacs function @samp{define-key}:
+
+@lisp
+(define-key evil-normal-state-map "w" 'foo)
+@end lisp
+
+@noindent This binds the key @kbd{w} to the command @samp{foo}
+in Normal state.  The file @code{evil-maps.el} contains all the
+key bindings.
+
+@defvar evil-normal-state-map
+The global keymap for Normal state.
+@end defvar
+
+@defvar evil-insert-state-map
+The global keymap for Insert state.
+@end defvar
+
+@defvar evil-visual-state-map

+@end defvar
+
+@defvar evil-operator-state-map
+The global keymap for Operator-Pending state.
+@end defvar
+
+@defvar evil-motion-state-map
+The global keymap for Motion state.
+@end defvar
+
+@noindent Each state also has a @dfn{buffer-local keymap},
+which is specific to the current buffer and has precedence over
+the global keymap.  These maps may be changed from a mode hook.
+
+@defvar evil-normal-state-local-map
+Buffer-local keymap for Normal state.
+@end defvar
+
+@defvar evil-insert-state-local-map
+Buffer-local keymap for Insert state.
+@end defvar
+
+@defvar evil-visual-state-local-map
+Buffer-local keymap for Visual state.
+@end defvar
+
+@defvar evil-replace-state-local-map
+Buffer-local keymap for Replace state.
+@end defvar
+
+@defvar evil-operator-state-local-map
+Buffer-local keymap for Operator-Pending state.
+@end defvar

+@menu
+* @samp{evil-define-key}::
+@end menu
+
+@node @samp{evil-define-key}
+@section @samp{evil-define-key}
+
+Finally, Evil provides the function @samp{evil-define-key} for adding
+state bindings to a regular keymap.
+
+@defun evil-define-key state keymap key def
+In @var{keymap}, create a binding from @var{key} to @var{def} in
+@var{state}.  @var{state} is one of @samp{normal}, @samp{insert},
+@samp{visual}, @samp{replace}, @samp{operator} and @samp{motion}.
+The other parameters are like those of @samp{define-key}.
+@end defun
+
+@noindent @samp{evil-define-key} can be used to augment existing
+modes with state bindings, as well as create packages for custom
+bindings.  For example, the following will create a minor mode
+@code{foo-mode} with Normal state bindings for the keys @kbd{w}
+and @kbd{e}:
+
+@lisp
+(define-minor-mode foo-mode
+  "Foo mode."
+  :keymap (make-sparse-keymap))
+
+(evil-define-key 'normal foo-mode-map "w" 'bar)
+(evil-define-key 'normal foo-mode-map "e" 'baz)
+@end lisp
+
+@noindent This minor mode can then be enabled in any buffers where
+the custom bindings are desired:
+
+@lisp
+(add-hook 'text-mode-hook 'foo-mode) ; @r{enable alongside @code{text-mode}}
+@end lisp
+
+@noindent If the minor mode is put into its own file @code{foo.el}
+with a @code{(provide 'foo)} statement, it becomes an Emacs package.
+
+@node Hooks
+@chapter Hooks
+
+A @dfn{hook} is a list of functions to execute.  Hooks are modified with
+the Emacs function @samp{add-hook}.  Evil provides entry and exit hooks
+for all of its states.
+
+@defvar evil-normal-state-entry-hook
+Run when entering Normal state.
+@end defvar
+
+@defvar evil-normal-state-exit-hook
+Run when exiting Normal state.
+@end defvar
+
+@defvar evil-insert-state-entry-hook
+Run when entering Insert state.
+@end defvar
+
+@defvar evil-insert-state-exit-hook
+Run when exiting Insert state.
+@end defvar
+
+@defvar evil-visual-state-entry-hook
+Run when entering Visual state.
+@end defvar
+
+@defvar evil-visual-state-exit-hook
+Run when exiting Visual state.
+@end defvar
+
+@defvar evil-replace-state-entry-hook
+Run when entering Replace state.
+@end defvar
+
+@defvar evil-replace-state-exit-hook
+Run when exiting Replace state.
+@end defvar
+
+@defvar evil-operator-state-entry-hook
+Run when entering Operator-Pending state.
+@end defvar
+
+@defvar evil-operator-state-exit-hook
+Run when exiting Operator-Pending state.
+@end defvar
+
+@defvar evil-motion-state-entry-hook
+Run when entering Motion state.
+@end defvar
+
+@defvar evil-motion-state-exit-hook
+Run when exiting Motion state.
+@end defvar
+
+@noindent When these hooks are run, the variables @samp{evil-next-state}
+and @samp{evil-previous-state} hold information about the states being
+switched to and from.
+
+@defvar evil-next-state
+The state being switched to.
+@end defvar
+
+@defvar evil-previous-state
+The state being switched from.

+* States::
+@end menu
+
+@node Motions
+@section Motions
+
+A @dfn{motion} is a command which moves the cursor, such as @kbd{w} and
+@kbd{e}.  Motions are defined with the macro @samp{evil-define-motion}.
+Motions not defined in this way should be declared with
+@samp{evil-declare-motion}.
+
+@defun evil-declare-motion command
+Declare @var{command} to be a motion.  This ensures that it works
+properly in Visual state.
+@end defun
+
+@defmac evil-define-motion motion (count args@dots{}) doc keyword-args@dots{} body@dots{}
+Define a movement command @var{motion}.  A motion can have any number of
+arguments, but the first argument, if any, has a predefined meaning as
+the @var{count}. It is a positive or negative number, or @code{nil}.
+The argument list is followed by the documentation string @var{doc},
+which is followed by optional keyword arguments:
+
+@table @code
+@item :type @var{type}
+The @var{type} determines how the motion works after an operator.  If
+@var{type} is @samp{inclusive}, then the ending position is included in
+the motion range.  If @var{type} is @samp{line}, then the range is
+expanded to linewise positions.  If @var{type} is @samp{block}, then the
+range is blockwise.  The default is @samp{exclusive}, which means that
+the range is used as-is.
+
+@item :jump @var{jump}
+If @var{jump} is @code{t}, then the previous position is stored in the
+jump list so it can be restored with @kbd{C-o}.  The default is
+@code{nil}.
+@end table
+
+The keyword arguments are followed by the @var{body}, which is where
+the motion's behavior is defined.  For instance:
+
+@lisp
+(evil-define-motion foo-forward (count)
+  "Move to the right by COUNT characters."
+  :type inclusive
+  (forward-char (or count 1)))
+@end lisp
+
+For more examples, you can view the source code for any command with
+@kbd{C-h k}.  For instance, @samp{evil-goto-line} may be viewed by
+typing @kbd{C-h k G} and following the file link.
+@end defmac
+
+@node Operators
+@section Operators
+
+An @dfn{operator} is a command which acts on the text moved over by a
+motion, such as @kbd{c}, @kbd{d} and @kbd{y}.  Operators are defined
+with the macro @samp{evil-define-operator}.
+
+@defmac evil-define-operator operator (beg end type args@dots{}) doc keyword-args@dots{} body@dots{}
+Define an operator command @var{operator}.  An operator must have at
+least two or three arguments, which have predefined meanings.
+@var{beg} is the beginning position, @var{end} is the ending position,
+and @var{type}, if given, is the type of the motion range.  The argument
+list is followed by the documentation string @var{doc}, which is
+followed by optional keyword arguments:
+
+@table @code
+@item :type @var{type}
+Make the input range be a certain @var{type}.  For example, an operator
+which only works with whole lines may set @var{type} to @samp{line}.
+
+@item :motion @var{motion}
+Use the motion @var{motion} instead of reading one from the keyboard.
+This does not affect the behavior in Visual state, where the selection
+boundaries are used instead.
+
+@item :repeat @var{repeat}
+If @var{repeat} is @code{t} (the default), then @kbd{.} will repeat the
+operator.  If @var{repeat} is @code{nil}, then the operator will not be
+repeated.
+
+@item :move-point @var{move-point}
+If @var{move-point} is @code{t} (the default), then the cursor is
+positioned at the beginning of the range.  If @var{move-point} is
+@code{nil}, then the original position is preserved.
+
+@item :keep-visual @var{keep-visual}
+If @var{keep-visual} is @code{t}, then the selection is not disabled
+when the operator is run in Visual state; it is up to the operator to do
+this.  The default is @code{nil}, which means that Visual state is
+exited automatically.
+@end table
+
+The keyword arguments are followed by the @var{body}, which is where the
+operator's actions on @var{beg} and @var{end} are defined.  For example,
+@samp{evil-rot13}, which is bound to @kbd{g?} and performs ROT13
+encryption on the text, may be defined as:
+
+@lisp
+(evil-define-operator evil-rot13 (beg end)
+  "ROT13 encrypt text."
+  (rot13-region beg end))
+@end lisp
+
+Pressing @kbd{g?w} will encrypt a word by calling @samp{rot13-region}
+on the text moved over by the @kbd{w} motion.
+@end defmac
+
+@node Text objects
+@section Text objects
+
+A @dfn{text object} is a special kind of motion which sets a beginning
+position as well as an ending position, such as @kbd{iw} and @kbd{a(}.
+In Visual state, text objects alter both ends of the selection.  Text
+objects are defined with the macro @samp{evil-define-text-object}.
+
+@defmac evil-define-text-object object (count args@dots{}) doc keyword-args@dots{} body@dots{}
+Define a text object @var{object}.  The first argument has a predefined
+meaning as the @var{count}: it is a positive or negative number.  The
+argument list is followed by the documentation string @var{doc}, which
+is followed by optional keyword arguments:
+
+@table @code
+@item :type @var{type}
+Use the type @var{type} after an operator.  In Visual state, this is the
+type of the selection.
+
+@item :extend-selection @var{extend-selection}
+If @var{extend-selection} is @code{t} (the default), then the text
+object always enlarges the current selection.  If @code{nil}, then the
+object replaces the selection.
+@end table
+
+The keyword arguments are followed by the @var{body}, which should
+evaluate to a list @code{(@var{beg} @var{end})} of two positions in the
+buffer.  For example, a text object which selects three characters
+following the current position could be defined as:
+
+@lisp
+(evil-define-text-object foo (count)
+  "Select three characters."
+  (list (point) (+ (point) 3)))
+@end lisp
+@end defmac
+
+@noindent Evil provides several functions which return a list of
+positions, for use in the definition of a text object.  These functions
+follow the rule that a positive @var{count} selects text after the
+current position, while a negative @var{count} selects text before it.
+
+@defun evil-inner-object-range count forward backward
+Return a text range @code{(@var{beg} @var{end})} of @var{count}
+``inner'' text objects (e.g., @kbd{iw}, @kbd{is}).  @var{forward} is a
+function which moves to the end of an object, and @var{backward} is a
+function which moves to the beginning.
+@end defun
+
+@defun evil-an-object-range count forward backward
+Return a text range @code{(@var{beg} @var{end})} of @var{count} text
+objects with whitespace (e.g., @kbd{aw}, @kbd{as}).  @var{forward} is a
+function which moves to the end of an object, and @var{backward} is a
+function which moves to the beginning.
+@end defun
+
+@defun evil-paren-range count open close &optional exclusive
+Return a text range @code{(@var{beg} @var{end})} of @var{count}
+delimited blocks (e.g., @kbd{i(}, @kbd{a(}). @var{open} and @var{close}
+are characters.  If @var{exclusive} is non-nil, then the delimiters are
+excluded from the range.  This function uses Emacs' syntax table and is
+only applicable for single-character delimiters; use
+@samp{evil-regexp-range} to match multiple characters.
+@end defun
+
+@defun evil-regexp-range count open close &optional exclusive
+Return a text range @code{(@var{beg} @var{end})} of @var{count}
+delimited blocks (e.g., @kbd{it}, @kbd{at}). @var{open} and @var{close}
+are regular expressions.  If @var{exclusive} is non-nil, then the
+delimiters are excluded from the range.
+@end defun
+
+@node Types
+@section Types
+
+A @dfn{type} is a transformation on a pair of buffer positions.  Evil
+defines the types @samp{exclusive}, @samp{inclusive}, @samp{line} and
+@samp{block}, which are used for motion ranges and Visual selection.
+Types are defined with the macro @samp{evil-define-type}.
+
+@defmac evil-define-type type doc keyword-args@dots{}
+Define a type @var{type}, described by the documentation string
+@var{doc}.  Then follows keyword arguments:
+
+@table @code
+@item :expand @var{expand}
+A function which takes two buffer positions and returns a list
+@code{(@var{beg} @var{end})} of expanded positions.
+
+@item :contract @var{contract}
+A function which takes two expanded buffer positions and returns a list
+@code{(@var{beg} @var{end})} of unexpanded positions.  Optional.
+
+@item :normalize @var{normalize}
+A function which takes two unexpanded buffer positions and returns a
+list @code{(@var{beg} @var{end})} of adjusted positions.  Optional.
+
+@item :injective @var{injective}
+If @code{t} (the default), then expansion is one-to-one -- i.e.,
+@var{expand} followed by @var{contract} always returns the original
+positions.  If @code{nil}, then several positions may expand to the same
+(for example, the @samp{line} type is one-to-many as it expands to the
+containing lines).
+@end table
+
+Further keywords and functions may be specified.  These are understood
+to be transformations on buffer positions, like @var{expand} and
+@var{contract}.
+@end defmac
+
+@node States
+@section States
+
+States are defined with the macro @samp{evil-define-state}.  The macro
+defines the necessary hooks, keymaps and variables for a state, as well
+as a toggle function @samp{evil-@var{state}-state} for entering the
+state, and a predicate function @samp{evil-@var{state}-state-p} which
+returns @code{t} when the state is active, and @code{nil} otherwise.
+
+@defmac evil-define-state state doc keyword-args@dots{} body@dots{}
+Define an Evil state @var{state}, described by the documentation string
+@var{doc}.  Then follows optional keyword arguments:
+
+@table @code
+@item :tag @var{tag}
+Mode line indicitor, e.g., @code{"<T>"}.
+@item :message @var{message}
+String shown in the echo area.
+@item :cursor @var{cursor}
+Cursor specification.
+@item :enable @var{enable}
+List of other modes and states to enable.  A state may enable another
+state's keymaps in addition to its own.
+@end table
+
+This is followed the @var{body}, which is executed whenever the state is
+enabled or disabled.  The state's predicate function may be used to
+distinguish between the two.

+@section Command properties
+
+Evil defines @dfn{command properties} to store information about
+commands, such as whether they should be repeated.  A command property
+is a @code{@var{:keyword}} with an associated value, e.g., @code{:repeat
+nil}.
+
+@defun evil-add-command-properties command &rest properties
+Add @var{properties} to @var{command}.  The properties should be
+specified as a list of keywords and values:
+
+@lisp
+(evil-add-command-properties 'my-command :repeat t)
+@end lisp
+@end defun
+
+@defun evil-set-command-properties command &rest properties
+Like @samp{evil-add-command-properties}, but resets all
+previous properties.
+@end defun
+
+@defun evil-get-command-property command property
+Return the value of a command property.
+@end defun
+
+@defmac evil-define-command command (args@dots{}) doc keyword-args@dots{} body@dots{}
+Define a command with command properties @var{keyword-args}.
+@end defmac
+
+@noindent For setting repeat properties, Evil provides the
+following functions:
+
+@defun evil-declare-repeat command
+Declare @var{command} to be repeatable.
+@end defun
+
+@defun evil-declare-not-repeat command
+Declare @var{command} to be nonrepeatable.
+@end defun
+
+@defun evil-declare-change-repeat command
+Declare @var{command} to be repeatable by buffer changes rather than
+keystrokes.

+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, La@TeX{} input
+format, SGML or XML using a publicly available
+DTD, and standard-conforming simple HTML,
+PostScript or PDF designed for human modification.  Examples
+of transparent image formats include PNG, XCF and
+JPG.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, SGML or
+XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML,
+PostScript or PDF produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
