Log Message:
Initial import of cvsd, a cvs pserver wrapper that chroots the pserver.

Based on the work by Eric Schnoebelen and virtus@ in pkgsrc-wip.

DESCR:
cvsd is a wrapper program for cvs in pserver mode. It will run 'cvs
pserver' under a special uid/gid in a chroot jail.

cvsd is run as a daemon and is controlled through a configuration
file. It is relatively easy to configure and tools are provided
for easily setting up a rootjail.

This server can be useful if you want to run a public cvs pserver.
You should however be aware of the security limitations of running
a cvs pserver. If you want any kind of authentication you should
really consider using secure shell as a secure authentication
mechanism and transport. Passwords used in cvs pserver are transmitted
in plaintext and this wrapper won't change that.

This server adds a layer of security to cvs. cvs is a very powerful
tool and is capable of running scripts and other things. By running
cvs in a rootjail it is possible to limit the amount of "damage"
cvs can do if it is exploited.  It is generally a good idea to run
cvsd without any write permissions to any directory on the system.
