These files are from the archives of NA4G.  They are available to anyone
that wishes to use them.  Readme files are present for all of them.
Some files are zipped using pkzip (.zip), some files are gnuzipped on dos
(.psz, etc files), and some are gnuzipped on unix (.ps.gz, etc).  One is
compressed on unix (.ps.Z).

Note.... .ps files are postscript printer files, and .lj files are laserjet
          printer files.  Most other are plain ascii .txt or .inf or .readme
          or .doc or .tex files.
