 # The XSI Curses standard requires all curses entry points to exist as
 # functions, even though many definitions would normally be shadowed
 # by macros.  Rather than hand-hack all that code, we actually
 # generate functions from the macros.
 #
 # This script accepts a file of prototypes on standard input.  It discards
 # any that don't have a `generated' comment attached. It then parses each
 # prototype (relying on the fact that none of the macros take function
 # pointer or array arguments) and generates C source from it.
 #
 # Here is what the pipeline stages are doing:
 #
 # 1. sed: extract prototypes of generated functions
 # 2. sed: decorate prototypes with generated arguments a1. a2,...z
 # 3. awk: generate the calls with args matching the formals
 # 4. sed: prefix function names in prototypes so the preprocessor won't expand
 #         them.
 # 5. cpp: macro-expand the file so the macro calls turn into C calls
 # 6. awk: strip the expansion junk off the front and add the new header
 # 7. sed: squeeze spaces, strip off gen_ prefix.
 #
