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