@ -277,6 +277,21 @@ In `dbdriver` and `dbuser` you can use the following variables:
If no name can be determined, the
numeric uid is used.
ENVIRONMENT
-----------
These variables obviate the need for command-line options in some
circumstances, allowing easier restricted usage through git-shell.
GIT_CVSSERVER_BASE_PATH takes the place of the argument to --base-path.
GIT_CVSSERVER_ROOT specifies a single-directory whitelist. The
repository must still be configured to allow access through
git-cvsserver, as described above.
When these environment variables are set, the corresponding
command-line arguments may not be used.
