Sorry for the long delay, but this little script is not dead. chm2pdf
0.0.3 is out: now with image support! (Intra-pdf links still dead, anyway. But I had suggestions on how to solve them.)
Download it here.
The script logic changed quite a lot, and it is still very rough
around the edges (0.1 is still -relatively- far). I'd like everyone of
you to test it as much as possible, since it is very likely that bugs
and quirks will occur. My knowledge of the CHM file format is
tentative at best.
As for the xtopdf collaboration, I have to reconnect myself with the xtopdf developer to see. I'd like to have chm2pdf in a decent state (0.1) before, anyway.
