+* Sharing, merging and synchronising item collections
+Every drill item is automatically given a persistent unique "ID" the first time
+it is seen by Org-Drill. This means that if two different people subsequently
+edit or reschedule that item, Org-Drill can still tell that it is the same
+item. This in turn means that collections of items can be shared and edited in
+a collaborative manner.
+There are two commands that are useful in this regard:
+1. =org-drill-strip-all-data= - this command deletes all user-specific
+   scheduling data from every item in the current collection. (It takes the
+   same optional 'scope' argument as =org-drill= to define which items will
+   be processed by the command). User-specific data includes scheduling dates,
+   ease factors, number of failures and repetitions, and so on. All items are
+   reset to 'new' status. This command is useful if you want to share your
+   item collection with someone else.
+2. =org-drill-merge-buffers= - When called from buffer A, it prompts you for
+   another buffer (B), which must also be loaded into Emacs. This command
+   imports all the user-specific scheduling data from buffer B into buffer A,
+   and deletes any such information in A. Matching items are identified by
+   their ID. Any items in B that do not exist in A are copied to A, in
+   the same hierarchical location if all the parent headings exist, otherwise
+   at the end of the buffer.
+An example scenario:
+Tim decides to learn Swedish using an item collection ( file) made
+publically available by Jane.  (Before publishing it Jane used
+'org-drill-strip-all-data' to remove her personal scheduling data from the
+collection.)  A few weeks later, Jane updates her collection, adding new items
+and revising some old ones. Tim downloads the new collection and imports his
+progress from his copy of the old collection, using 'org-drill-merge-buffers',
+using the new collection as buffer A and the old one as buffer B. He can then
+discard the old copy. Any items HE added to HIS copy of the old collection
+(buffer B) will not be lost -- they will be appended to his copy of the new
+Of course the sharing does not need to be 'public'. You and a friend might be
+learning a language or some other topic together. You each maintain a card
+collection. Periodically your friend sends you a copy of their collection --
+you run =org-drill-merge-buffers= on it, always using your own collection as
+buffer B so that your own scheduling progress is carried over. Other times you
+send your friend a copy of your collection, and he or she follows the same

-- get tooltips to work for old/new/etc counts during review?
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
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.
