18# 18/01/2001 - Cleanups
19# Functions prototyped as foo(void) same as foo()
20# Stop eval'ing where we don't need to.
21# -- huggie@earth.li
22
23# 27/06/2001 - Allowed whitespace after initial "/**" and
24# allowed comments before function declarations.
25# -- Christian Kreibich <ck@whoop.org>
26
27# Still to do:
28# - add perldoc documentation
29# - Look more closely at some of the scarier bits :)
30
31# 26/05/2001 - Support for separate source and object trees.
32# Return error code.
33# Keith Owens <kaos@ocs.com.au>
34
35# 23/09/2001 - Added support for typedefs, structs, enums and unions
36# Support for Context section; can be terminated using empty line
37# Small fixes (like spaces vs. \s in regex)
38# -- Tim Jansen <tim@tjansen.de>
