I thoguht it was easier for me to go the other way.  No doubt
integration with pysim would have been cleaner.  The problem is that
there are too many tools.  For most of my manual/interactive work with
SIM cards and other smart cards I use cyberflex-shell from
git://github.com/henryk/cyberflex-shell.git which allows you to enter
raw APDUs on a command line and have modules for various card types that
implement card-specific features.  So the 'cleanest' implementation
would probably have been to merge all of them, but that requires time...

Regards,
	Harald
