Released 1991 by US-CERL 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.
