Ⅳ. 文档说明

A Vim plugin for automatically saving backup versions in RCS whenever a file is saved.  You can compare to any revision as well.
keywords: VCS, version control system, incremental saving, automatic versioning, automatic journalling or journaling, or autosave backups with versions.

The maintainer is Juan Frias (juandfrias at gmail.com)

What's RCS? It's the Revision Control System, a set of programs used for keeping many versions of a file. See http://www.gnu.org/software/rcs/rcs.html

The RCS programs are freely available at http://www.cs.purdue.edu/homes/trinkle/RCS/

Be careful if you really use RCS as your production file control, it will add versions like crazy.  See the g:rvMode option to have more control over when a save is added to the revision file.

rcs-menu.vim by Jeff Lanzarotta is handy to have along with this (vimscript #41).

Inspired by savevers.vim by Ed Ralston (vimscript #89).

Mapped Keys:
               <Leader>rci     This will create an initial RCS file.  Only
                                      necessary when you have the script set to
                                      save only when a previous RCS file exists.
               <Leader>rlog    To access the saved revisions log.  This works as
                                      a toggle to quit the revision windows too.

               <enter>         This will compare the current file to the
                                    revision under the cursor (works only in
                                    the revision log window)

               <Leader>older   does a diff with the previous version

               <Leader>newer   does a diff with the next version

You probably want to map these in your _vimrc to something easier to type,
like a function key.  Do it like this:
"re-map rcsvers.vim keys
map <F9> rci
map <F8> rlog
map <F5> older
map <F6> newer

You may need to set the following shell(environment) variables, you'll get a warning if so:
user name:

    LOGNAME=myusername

timezone:  

    TZ=EST5EDT 

Look here if you have problems with Daylight Saving Time (DST) with RCS after 2007 on Microsoft Windows:  http://support.microsoft.com/kb/932590

2013-10-16: Roger says: This seems to have broken between vim 7.3 and vim 7.4, on Windows, when saving versions of files where the file is in a folder with parentheses e.g. ()

Backing out to vim 7.3 fixed the problem.

If you can help figure it out, put something on the wiki page (link at the top of this page)
