17# 18/01/2001 - Cleanups
18# Functions prototyped as foo(void) same as foo()
19# Stop eval'ing where we don't need to.
20# -- huggie@earth.li
21
22# 27/06/2001 - Allowed whitespace after initial "/**" and
23# allowed comments before function declarations.
24# -- Christian Kreibich <ck@whoop.org>
25
26# Still to do:
27# - add perldoc documentation
28# - Look more closely at some of the scarier bits :)
29
30# 26/05/2001 - Support for separate source and object trees.
31# Return error code.
32# Keith Owens <kaos@ocs.com.au>
33
34# 23/09/2001 - Added support for typedefs, structs, enums and unions
35# Support for Context section; can be terminated using empty line
36# Small fixes (like spaces vs. \s in regex)
37# -- Tim Jansen <tim@tjansen.de>
