better documentation and is easier to debug.

-
-    [uwsgi]
-    plugins = cgi
-    uid = aur
-    processes = 1
-    threads = 8
-    env = GIT_HTTP_EXPORT_ALL=
-    env = GIT_PROJECT_ROOT=/srv/http/aurweb
-    cgi = /usr/lib/git-core/git-http-backend
+   Sample systemd unit files for fcgiwrap can be found under conf/.
