+       This is the distribution of Franz Lisp Opus 38.92 for the CCI "tahoe"
+machine.  It should be configurable as a VAX or 68000 version, but this
+has not yet been tested.
+       Before the system can be compiled, a change is necessary to /lib/c2,
+the C-compiler's optimizer phase. Without this change, the optimizer dumps
+core when run through a pipe:

+       Another special condsideration is the WCS version in use. If bignum
+math with negative numbers (try "(quotient 9999999999999999999 -9)") gives
+incorrect results, then you are using an outdated WCS and should attempt to
+obtain a newer version from CCI.
