Sorry for the delay but I found building redistributable python apps in Windows is a pain in the *** ;(
In the meantime, though, I went further, so now KCC build ePub2.0-valid files
, then you can choose to give them to kindlegen
or to stay with them alone (e.g. if you own a Kobo :P )
The GUI should make all the dirty work on your behalf, providing you have kindlegen.exe
in your PATH (e.g. you can copy it to c:\Windows\).
