>From file README:
How to build SPS:
    1. In order to compile and install SPS, first unbundle the four shell
       archive files.

4 shars...  From the net: alt.sources:

 2373 New release of SPS (support for SunOS 4.0, 4.1 and DEC 3100's)
 2374 SPS for SunOS4.1 and DEC 3100's - Shar 1 of 3
 2375 SPS for SunOS4.1 and DEC 3100's - Shar 2 of 3
 2376 SPS for SunOS4.1 and DEC 3100's - Shar 3 of 3

3 shars...

Can you help me get this compiled?
