-# macroExpander.py

-#

-# Example pyparsing program for performing macro expansion, similar to 

-# the C pre-processor.  This program is not as fully-featured, simply

-# processing macros of the form:

-#     #def xxx yyyyy

-# and replacing xxx with yyyyy in the rest of the input string.  Macros

-# can also be composed using other macros, such as

-#     #def zzz xxx+1

-# Since xxx was previously defined as yyyyy, then zzz will be replaced

-# with yyyyy+1.
