I did some quick research.
I don't use that .lpr, but build_lcl_chm.sh
How do you extract the index? with "extractindex lcl.chm" or extract lcl.chm default.hhk ?
I had a quick look, and I notice two things:
- the binary one (extractindex) is a lot larger.
- Windows seems to use the textual one
- the binary one has keyword attribute equal to the name attribute where IMHO that is wrong. Question is only if that is wrong in chmls or in the original index (and thus fpdoc).
I guess I have my homework for the weekend cut-out.
