# Caution:  This script crudely removes parentheses, braces
# and semicolons from the original source.  If any of these
# characters are contained in comments or character literals
# then they will also be affected.  Check the output carefully.
#
# Also, it is your responsibility to ensure that subroutines
# have explicit 'return's as appropriate.  The script cannot
# assume that every subroutine needs one.  For code space
# reasons I sometimes replace 'call / return' pairs with
# a 'goto'.  Another possibility is that the subroutine
# finishes with a 'retlw'.
#
# This script assumes C++ style comments.
