Currently, the approach we take for figuring the location of part files
is this: all files a "model builder" might need to use directly belong
in /parts/. This includes all composite parts, atomic parts, shortcuts,
and segments. Other files go in /parts/s/, /p/, or /p/48/.

A very simple way to handle this is to define a value for the LDRAW_ORG
line that appears in every file in the parts library. Currently, most
files have a line that looks like:
0 LDRAW_ORG Part UPDATE 2001-03
Right now, the legal 'filetypes' are Part, Shortcut, Subpart, and
Primitive. We could easily add Segment to the list of types.
The only catch is these 'filetypes' are currently derived from a
combination of directory and special characters in the part title. :\
This could be changed -- the Parts Tracker could be enhanced to include
a 'file type' datum.
