# Given one or more C declarations, this program converts them to  an  extern #
# declarations.  This entails replacing any initial "static" or "global" with #
# "extern", and stripping away any initializers.  The current  implementation #
# works  best  with one-line declarations; some multi-line declarations won't #
# be completely transformed.  This program is intended  to  be  run  from  an #
# editor to rewrite a chunk of the program.                                   #
