The TALC compiler consists of a set of tools for Talx86, a variant of
typed assembly language for the IA32 architecture, and some front ends
that demonstrate its viability as a target language.  Currently the
there are two front ends: popcorn and scheme.  There used to be a
third front end for KML, but it was broken by some recent changes to
Talx86.  A major rework of the KML front end is underway.

See the file INSTALL for instructions on building and running TALC.
