[l2h] help files (.hhp .hhc .hhk)

[Oscar Germán Duarte Velasco]

I need to create help files and I want to use latex/latex2html to do
that. I have found a previous message in this list
(http://tug.org/mailman/htdig/latex2html/2002-August/002008.html)
concerning with this topic, but no further references, so I have tried
to do it by myself, and I want to share with you the results.

The problem is to create 3 files (.hhp .hhc .hhk) whose format are
explained at:
http://www.wxwindows.org/manuals/2.4.2/wx499.htm#helpformat

In the message of August-2002 Ross Moore suggested a postproccesing of
the contents.pl or labels.pl files... I have tried a different
approach... I have used the latex2html-init file and the
custom_title_hook subroutine.

I do not know in depth the latex/latex2html code, and I have not written
any previous perl subroutine... so I am sure you can do a better job...
My init file is bellow. You will find some weak points:

1) The directory and file names managment
2) I must to add manually a "</UL>" line at the end of the .hhc and .hhk
files
3) No Anchors are proccessed, just file names
4) I must replace in the html files the ALIGN="MIDDLE" statments for
ALIGN="CENTER". A simple grep instruction do that. Why? because I am
using the wxWindows library (www.wxwindows.org), and the wxHTML class of
that library does not recognize the "MIDDLE".

I hope this wil be useful for anybody... at least it has been useful for
me...
