Subject: [PATCH] git-remote-mediawiki: display message when launched directly
Date: Tue, 11 Jun 2013 15:38:48 +0200 [thread overview]
Message-ID: <1370957928-19303-1-git-send-email-celestin.matte@ensimag.fr> (raw)
Users may be confused when they run the perl script directly.
A good way to detect this is to check the number of parameters used to call the
script, which is never different from 2 in a normal use.
Display a proper error message to avoid any confusion.
