# This Perl script will take api.lst, the list of APIs to wrap, and it 
# will build the Unicode list of files, the fixaw-generated list, and 
# the DEF file. This allow new APIs to be added by making one change in
# api.lst and calling it a day.

# NOTE: It has been a while since I have built a Perl script, do not make fun of it!
