-" Handling of special buffers
-"
-" Author: Peter Odding <peter@peterodding.com>
-" Last Change: May 19, 2013
-" URL: http://peterodding.com/code/vim/misc/
-"
-" The functions defined here make it easier to deal with special Vim buffers
-" that contain text generated by a Vim plug-in. For example my [vim-notes
-" plug-in] [vim-notes] generates several such buffers:
-"
-" - [:RecentNotes] [RecentNotes] lists recently modified notes
-" - [:ShowTaggedNotes] [ShowTaggedNotes] lists notes grouped by tags
-" - etc.
-"
-" Because the text in these buffers is generated, Vim shouldn't bother with
-" swap files and it should never prompt the user whether to save changes to
-" the generated text.
