Can't believe I've only just found out about Kobo patching after having had one for a couple of years. Back in the Sony PRS days I used to play around a lot with patches.
Anyways, I'm a Windows user but prefer my Unixy environments, including doing as much as possible with Cygwin on Windows. This little patch lets me run kobopatch from Cygwin using kobopatch.sh instead of needlessly needing me to fire up a CMD shell in the right folder
