i've been hacking latex2html's source code (version 2002-2-1) about a
bit (just to make it do what i want), and am going to try turning some
what i've done into useful patches. it looks to me as if some of the
files in versions/html*.pl are obsolete: if i could have that
confirmed/denied, then i could be sure i'm preparing patches for just
the relevant files.
specifically ...
-rw-r--r--1 phil phil20274 Jul 11 1999 versions/html2_1.pl
-rw-r--r--1 phil phil 7704 Sep 27 06:15 versions/html2_2.pl

-rw-r--r--1 phil phil47036 Apr 13 2002 versions/html3_2.pl
-rw-r--r--1 phil phil60307 Apr 13 2002 versions/html4_0.pl
-rw-r--r--1 phil phil60964 Apr 13 2002 versions/html4_01.pl
-rw-r--r--1 phil phil60964 Aug 21 2002 versions/html4_1.pl
a) it appears that these are never used:
html2_1.pl html2_2.pl html3_1.pl
Correct, insofar as HTML versions 1, 2.1, and 2.2 are never
used anymore, having been superseded long ago by HTML 3.2 and 4.x .
Similarly 3.1 is out-dated, implementing MATH tags that
never got universal acceptance.
b) html4_01.pl and html4_1.pl are identical to one another.
html4_01.pl is never used, because if you say `-html_version 4.01',
the code rounds 4.01 to 4.0 so you get the same result as if you'd
said `-html_version 4.0'. i'd guess that the idea behind html4_1.pl
is to let the user say `-html_version 4.1' when they want HTML 4.01
(this doesn't quite work, because the DOCTYPE mentions 4.1).
Yeah, that was the idea.
OK, so there needs to be a small patch to get the DOCTYPE correct.
_if_ i have all that right, then the best course of action would be
to stop the code rounding 4.01 to 4.0, and delete html4_1.pl.
The same trick was used with 3_1 really being 3.01 (I think).
For compatibility with any existing documents or scripts calling
LaTeX2HTML, it would be best to catch 4_1 and make it 4.01
where needed, as well as stopping the rounding.
There is no future compatibility problem, as the W3C have effectively
frozen HTML at 4.01 --- as far as I can recall.
Future development is in XHTML and XML.
thanks in advance for any guidance.
Hope this helps,
Ross Moore
