md5 contains the MD5 hash program used to generate the contents of the
top-level file `checksums'.
fpsim.tar contains a floating-point simulator for 7th Edition, donated by
Henry Spencer. Here are the details from the man page:
This system provides for software emulation of floating-point
instructions if floating-point hardware is not present. The
kernel code in question simulates an FP11 floating-point
processor by intercepting illegal-instruction traps and
decoding and interpreting the floating-point opcodes.
This simulator is derived from Bell's, which used signal(2)
and was compiled into the user program. Mike Tilson of HCR
thought of and did the original kernel-mode simulator;
this improved variant by Henry Spencer.
