### Executive summary

Jonathan Kamens originally wrote and released code for adding support
for Perforce to VC mode in Emacs 21. His files can be found here:

Jonathan no longer actively uses Perforce and is no longer able to
support these files. Another Perforce user, Magnus Henoch, has branched
his own version of these files with some fixes. If Jonathan's version
doesn't work for you, you can find Magnus's version at:

### More information

This is Jonathan Kamens's original announcement about vc-p4 from the
perforce-user email list in January 2002:

These files, an alternative to p4.el, make the standard Emacs VC
(Version Control) commands support Perforce, e.g., for people who are
familiar with Emacs VC commands and prefer to be able to continue to use
them rather than learning the completely new set of commands provided by
p4.el.

These files will work with the version of VC mode included in Emacs 21
and with any other Emacs variant which uses the version of VC mode
included in Emacs 21. These files will NOT work with the version of VC
mode included in Emacs 20 or earlier.

The functionality provided by this VC support is a subset of the
functionality provided by p4.el. If you'd like to be able to use both
the VC Perforce support and p4.el, you can do so by loading them both
into Emacs and setting p4-do-find-file to nil. If you do this, then you
will use VC commands for Perforce operations related to individual files
but p4.el commands for Perforce operations not related to individual
files (e.g., "p4 submit", "p4 client", "p4 user", etc.).

The file p4-lowlevel.el provides a low-level interface to "p4" commands
from within Emacs; if you do Emacs programming and might benefit from
being able to perform Perforce operations in Emacs-lisp code, you might
find this file useful even if you don't want to use vc-p4.el.

Note that I don't work for Perforce and this code is supported and
maintained by me, not by Perforce.

Please let me know if you have any questions. And \*please\* report any
bugs you find in this code!

Development of this code was sponsored by my employer, Curl Corporation
(http://www.curl.com/). Yes, we use Perforce :-).

Enjoy!
