Actually, I have a rather silly -o flag at the moment, which lets one
specify an output directory.  Maybe I should just make this an output
path (including filename), which would allow one to specify an
alternate filename for the "sugarized" icon.  Would this be
appropriate for the use case you had in mind, or would it truly be
better to rename the old backup instead?  I'm honestly not too worried
about corruption of files, since the resulting SVG should remain fully
editable after conversion, and running the script multiple times
shouldn't be a problem either.  Only testing, of course, can validate
my optimism...
