augmenting them here and there. For now, it works more-or-less similar to unix/windows freeze, generating a config.c file, but storing modules in PYC resources. A template project is also copied. The hooks are in place to freeze by merging shared libraries so you can freeze without a C compiler/linker, but this does not work yet.
