the preprocessed source, bzip2-ed
The uncompressed (preprocessed) file has about 225697 lines or 11470145 bytes
with 157 routines. The two biggest routines are at the end (start_module_melt &
initialize_module_cdata). They are filling a structure with more than one
thousand members, each member being a structure of a few words length.
