From 5ada8687995fadea01f755d52ceec58337d003a3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9lestin=20Matte?= Date: Tue, 11 Jun 2013 15:38:48 +0200 Subject: git-remote-mediawiki: display message when launched directly MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
