Gitolite now has a mechanism for allowing access control for arbitrary
external commands, as long as they are invoked via ssh and present a
server-side command that contains enough information to make an access control
decision. The first (and only, so far) such command implemented is rsync.
decision.
Note that this is incompatible with giving people shell access as described in
`doc/6-ssh-troubleshooting.mkd` -- people who have shell access are not
subject to this mechanism (it wouldn't make sense to try and control someone
who has shell access anyway).
Please see the config files (both of them) for examples and usage.
In general, external commands require changes in one or both the config files;
the sample files in `conf/` double as documentation, so you should look there
for examples and usage.
Commands implemented so far are:
* rsync
* svnserve (see next section for a brief description; this has been
contributed by Simon and Vladimir)

##### svnserve
If you are transitioning from SVN to gitolite, and have a lot of users using
public-key authentication with SVN, this feature may be useful to you. Once
you migrate all users' public keys into gitolite, you can set the `$SVNSERVE`
variable in `~/.gitolite.rc` to tie `svnserve` with gitolite's authentication
system. Assuming you installed gitolite to the same user as the one you used
for SVN, SVN connectivity will be retained, and users will be able to use
both SVN and git using the same SSH configuration.
