+#!/usr/bin/ruby
+# This is a wrapper to msgmerge, it executes msgmerge with the given arguments, and
+# if msgmerge output is empty, prints the content of the file named the first
+# argument. otherwise it prints the output of msgmerge. The wrapper should be
+# "compatible" with the real msgmerge if msgmerge output is non-empty, or if the
+# first argument is the defpo file (instead of an option, or --)
+#
+# The path to msgmerge can be specified in env variable REAL_MSGMERGE_PATH
+#
+# The purpose is to provide a workaround for ruby-gettext, which treats empty output
+# from msgmerge as error in the po file, where it should mean that no modification
+# is needed to the defpo. For updates on the issue follow
+# http://rubyforge.org/pipermail/gettext-users-en/2008-June/000094.html
