Software

Selection of the following options preceded by a binary icon retrieves a compressed UNIX tar file, a self-extracting DOS executable, or a BinHex-encoded self-extracting Macintosh executable. A README file containing installation instructions is included with each of the software distribution files. There are separate README files for the UNIX, DOS, and Macintosh distributions.

The Free Software Foundation's gunzip is necessary to uncompress the UNIX tar files available below. However, some World Wide Web browsers automatically uncompress retrieved files. Thus, running gunzip as stated in the installation instructions may be unnecessary.

Aladdin Systems' StuffIt Expander, a freeware product, is necessary to decode the Macintosh distribution file available below.
