git-daemon --base-path

Browse Source 
Tommi Virtanen expressed a wish on #git to be able to use short and elegant
git URLs by making git-daemon 'root' in a given directory. This patch
implements this, causing git-daemon to interpret all paths relative to
the given base path if any is given.

git-daemon will refuse to start when this option is enabled and no
whitelist is specified.
--base-path::
Remap all the path requests as relative to the given path.
This is sort of "GIT root" - if you run git-daemon with
'--base-path=/srv/git' on example.com, then if you later try to pull
'git://example.com/hello.git', `git-daemon` will interpret the path
as '/srv/git/hello.git'. Home directories (the '~login' notation)
access is disabled.
--export-all::
Allow pulling from all directories that look like GIT repositories
(have the 'objects' and 'refs' subdirectories), even if they
