In current release there are plenty of *.profile files, but there is no single documentation for it. Man page is very descriptive: https://github.com/OpenSC/OpenSC/blob/master/doc/files/pkcs15-profile.5.xml

Some syntatic information can be extracted from the https://github.com/OpenSC/OpenSC/blob/master/src/pkcs15init/profile.c file, but semantic one are almost impossible to figure out.

For someone who is trying to customize the card it is really painful to do it, especially when he is comparing them with PKCS#15 https://www.foo.be/docs/opensst/ref/pkcs/pkcs-15/pkcs-15v11d1.pdf

Also according to existing files themselves, they are formatted in terribly inconsistent way (even in single file there spaces/tabs mixed indents). Another case are magic numbers spreded everywhere.

@viktorTarasov @frankmorgner @okirch I would be grateful if you will do something with that.
