tools/build/fingerprint_c.pl - Create fingerprint.c
% perl tools/build/fingerprint_c.pl > src/fingerprint.c
The PBC_COMPAT file is used to maintain Parrot bytecode compatability. During the build process it is parsed by fingerprint_c.pl to produce a fingerprint of the state of Parrot.
Note that this is only done for development versions of Parrot, i.e. the file DEVELOPING exists. Releases include a non-dynamic fingerprint.c.
