Here are the extensions we use in this archive and their explanations:

<no extension>	-  directory
.txt		-  an ascii text file
.etx		-  an ascii text file in a particular format called
		   "structure-enhanced text". Browser programs can beautify
		   these files.
.abs		-  an ascii text file containing abstracts of the other files
		   in its directory
.hqx		-  an ascii text file which contains an image of a Macintosh
                   file. Use Binhex 4.0, StuffIt, Compact Pro, or a variety
		   of other utilities to convert these files from encoded text
		   into applications and documents.
		   Compact Pro is recommended as it is more robust.
.shar		-  shell archive. Can be converted into text documents on
  		   a Unix system.
.uu		-  a uuencoded file which can be converted into a binary
                   file by running uudecode on a Unix system

All of these files can be transferred with ASCII mode FTP.

After the file has been transferred to your mac and converted from binhex,
you may see additional unfamiliar kinds of file. These are mainly archive
formats which allow files to be posted here in a compressed, more convenient
to manage form. Some common extensions are:

.cpt		-  Compact Pro archive (see /util)
.pit		-  PackIt II archive (obsolete). Deconvert with one of the
                   other archivers, using special menu items.
.sea		-  self-extracting archive, an application which creates new
                   files when run. No additional software is necessary.
.sit		-  StuffIt archive
SITD		-  actually a file type, this indicates Stuffit Deluxe
