After working some months with version 2.2.1 I saw some bugs which
should be fixed. Especially the CAL converter did not work as expected
in every case. Now I tried to use a regular expression comparison to
enforce a correct detection of real CAL blocks in IL source code.

I have some more small improvements in mind and a new release will
come during next month. Just ask me if you need a preliminarily release
with the current fixes ask me.
