;;; Synched up with: not in GNU Emacs.

;;; Thanx to:

;;     Tore Olsen <toreo@tihlde.hist.no> for some general fixes.
;;     Steve Sanbeg <sanbeg@dset.com> for navigation functions and
;;          some Emacs fixes.

;;; ToDo:

;; - rewrite function names and shortcuts.
;; - autofill changelog entries.
;; - customize rpm-tags-list and rpm-group-tags-list.
;; - get values from `rpm --showrc'.
;; - ssh/rsh for compile.
;; - finish integrating the new navigation functions in with existing stuff.
;; - use a single prefix consistently (internal)

;;; Commentary:

;; This mode is used for editing spec files used for building RPM packages.
;;
;; Most recent version is available from:
;;  <URL:http://www.tihlde.org/~stigb/rpm-spec-mode.el>
;;
;; Put this in your .emacs file to enable autoloading of rpm-spec-mode,
;; and auto-recognition of ".spec" files:
;;
;;  (autoload 'rpm-spec-mode "rpm-spec-mode.el" "RPM spec mode." t)

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
