# git caching proxy
+# Suitable only for exposing to semi-trusted clients: clients are not
+# supposed to be able to take over the server. However, clients can
+# probably deny service to each other because the current
+# implementation is not very good at handling various out-of-course
+# situations (notably, clients which are too slow).
+
# usage: run it on some port, and then clone or fetch
# "git://<realhost>:<realport>/<real-git-url>[ <options>]"
# where <real-git-url> is http://<host>/... or git://<host>/...
# fetch=try use what is in the cache if the fetch/clone fails
# timeout=<seconds> length of time to allow for fetch/clone
+# example inetd.conf line:
+# 9419 stream tcp nowait git-cache /usr/bin/git-cache-proxy git-cache-proxy
+# you'll need to
+# adduser git-cache
+# mkdir /var/cache/git-cache-proxy
+# chown git-cache /var/cache/git-cache-proxy
