Notes for those upgrading from earlier Debian packages of tex4ht
----------------------------------------------------------------

mk4ht in VERSIONS LATER THAN 20071203:

The perl script "mk4ht" depends on various scripts that are part of
the TeX4HT system. The newer versions of "mk4ht" search for these
scripts using "kpsewhich". On Debian these scripts are installed in
/usr/share/tex4ht. Thus the variable "TEXINPUTS.mk4ht" is defined as
this path in "/etc/texmf/texmf.d/80tex4ht.cnf".

ADDITION of xtpipes.jar in VERSIONS LATER THAN 20070821:

The java jar file "xtpipes.jar" has been added in the directory
/usr/share/tex4ht. This allows the entries related to xtpipes in
tex4ht.env to become operational *if* a suitable java runtime 
which supports java version 1.5 or greater is installed. On Debian
this is currently only "gij" (version 4.1 or greater) so that package
has been added as a "Suggests:" to "tex4ht". We may increase this
dependency level is "xtpipes" becomes more integral to the TeX4HT
system.

UPGRADING FROM VERSIONS EARLIER THAN 20051130:

The current version of the package is split into a arch-dependendent
"tex4ht" package and an architecture independent "tex4ht-common". This
split is for the convenience of the mirrors since the latter provides
the bulk of the TeX4ht system.

The DFSG non-free documentation has been removed from the package. In
its place the documentation provided links to the author Eitan M. Gurari's
web site. In addition a sample file has been provided that also
contains the documentation in the "html/" sub-directory of this
directory.

UPGRADING FROM VERSIONS EARLIER THAN 20030426:

The current version of the package uses a modified version of the tex4ht.env
configuration file included with the upstream sources. This includes some new
functionality, in particular 'tagged' sections that are used by some of the
scripts for generating MathML, OpenOffice.org and other output formats.
Although the programs should continue to work with earlier versions of
tex4ht.env, upgrading to the currently shipped version is recommended.

UPGRADING FROM VERSIONS EARLIER THAN 20000703:

1. Configuration file htfcss.env is no longer used.  Instead, entries for CSS
files are included at the end of the .htf font files themselves.  See
/usr/share/doc/texmf/tex4ht/mn20.html for more details.  This will not affect
you unless you have added your own entries to htfcss.env, or have created your
own .htf font files.

2. The 'd...' line in configuration file tex4ht.env has been replaced by a
'l...' line.  This is explained in the 'bugfixes' page of the manual.  (But
neither 'd...' nor 'l...' lines are used by default in the Debian package, as
they are not required with kpathsea file searching, so this should not affect
you.)

3. The 'g...' line in configuration file tex4ht.env now forces generation of
'.png' instead of '.gif' files for maths symbols etc, because this seems more
in keeping with Debian's free software philosophy.  See README.Debian for more
notes.

4. New scripts 'httex', 'htlatex' and 'httexi' are provided, as alternatives
to the 'ht' script for tex/latex/texinfo files that do not explicitly load the
tex4ht style file or include the tex4ht configuration commands.  See the
manual (/usr/share/doc/texmf/tex4ht/mn.html) for more details.
