I’m pretty sure there is already a program (‘ckformat' I think?) that reads the header and reports the type. It’s even used in the shell script for launching squeak, at least in the interpreterVM world.

Take a look at http://squeakvm.org/cgi-bin/viewvc.cgi/squeak/trunk/platforms/unix/cmake/squeak.in?view=markup
