This directory contains an Unlambda debugger written in Perl.  This
can be used as an interpreter (although it is rather slow), but it is
most useful for understanding the step-by-step details of Unlambda
evaluation.

To run it, just type

  perl -w unlambda.pl inputfile.unl

where inputfile.unl is the Unlambda program you want to analyze.  The
debugger's commands are listed in the comments at the beginning of the
program itself.
