* Use "#!/usr/bin/env perl" instead of "#!/usr/bin/perl", as this is better practice (it allows e.g. /usr/local/bin/perl to work when executing via the shebang) * Use "use strict" and "use warnings" * Declare variables with "my" as required by "use strict" * Take an optional "srcdir" argument so that the scripts can find the icon files in a location other than ./icons/ -- this will make building outside of the source tree possible in the future * Add a "this is a generated file" banner to the output, so that it can be clearly recognized as a machine-generated file that should not be hand-edited * Minor regex tweaks
