# This script merges a script file with a desktop file containing
# metadata about the external tool. This is required in order to
# have translatable tools (bug #342042) since intltool can't extract
# string directly from tool files (a tool file being the combination
# of a script file and a metadata section).
#
# The desktop file is embedded in a comment of the script file, under
# the assumption that any scripting language supports # as a comment
# mark (this is likely to be true since the shebang uses #!). The
# section is placed at the top of the tool file, after the shebang and
# modelines if present.
