Suggestions:
Do a one-time scan of the LDRAW directory, and build a translation table in
memory between your way of file name normalization, and the actual, file
system, file names. Then you just go through this table for every
reference... (Hashed array?)
Or build this table incrementally when each part is referenced for the first
time...
Or make a utility to rename a directory hierarchy in a normalized way...
