The FreeBSD project uses the Perforce version control system to manage experimental projects that are not ready for the main Subversion repository.
While Perforce is a commercial
product, the client software for interacting with the server
is freely available from Perforce. It can be easily installed
on FreeBSD via the devel/p4 port or can be
downloaded from the Perforce web
site at http://www.perforce.com/downloads/helix#clients,
which also offers client applications for other OS's.
While there is a GUI client available, most people use the
command line application called p4. This
document is written from the point of view of using this
command.
Detailed documentation is available online at https://www.perforce.com/perforce/doc.current/manuals/p4guide/index.html.
Reading the “Perforce User's Guide” and
“Perforce Command Reference” is highly
recommended. The p4 application
also contains an extensive amount of online help accessible
via p4 help.
The FreeBSD Perforce server is
hosted on perforce.freebsd.org, port
1666. The repository is browsable online
at http://p4web.freebsd.org.
