The tcl/tk scripts I've done grabs everything, then you tell it incrementally what functions to "loose", things like "__.*" and "mtx.*" is a good start. You can also add lines which are missing. Since the script have no idea where calls through pointers go it adds a pseudofunction with a star prefixed, and it's your own responsibility to link these up. It's not great, but it works. It would be neat if somebody write code to use the GUI bits of Tk so that you could point and click more etc. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
