These files comprise the entirety of GRASS4.0 (src, src.alpha,
src.related, src.contrib).  They are generated from a compressed
cpio file, split into 1-megabyte chunks.

To use these files, acquire all of them.  Then "cat" the files
together, uncompress the combination, and un-cpio the archive:

     cat grass.???? | zcat | cpio -icdmu
 
WARNING: these files are BIG.  There are 11 files which when concatenated
are over 10MB in length.  This file when uncompressed is simply huge (on
the order of 26MB, I believe).  To un-cpio the resultant file, you'll need
at least that much space in excess, to hold the extracted files.  Be sure
that you are in the target directory for the GRASS source code when you
issue the command above!

2002: Note for Linux users:
      cat grass.???? | zcat | cpio -id

... will extract the files.
