I suggest naming the test file after what it's functionally doing, not
based on the object we are testing. So maybe test_isoinfo.py. Similarly
move the isoinfo stuff out of generic named util.py and into its own
file, probably just into test_isoinfo.py unless there's a clear
different user on the horizon.

Interesting, apparnetly regex is an alternate python regex library
implementation. It's not from the standard library though, that's
'import re', which you can probably just sed replace at it will work
just as well.

Otherwise this looks fine, most important thing is that it works. I
recommend getting a pylint setup though, it will point out certain
things like not using 'type' as a variable name because it overwrites
the global 'type' function in the local scope
