Installation
The programs hevea and hacha are written in
Objective Caml. Thus, you
really need Objective Caml (version 2.00 or further) to compile them.
However, a Red Hat 5.2
binary distribution
is also available, it does not require an Objective Caml installation
and can be installed on most Red Hat Linux PC's.
HEVEA users may instruct the program not to process a
part of the input (see section 6). Instead, this part is
processed into a
.gif file and HEVEA outputs a link to the image file.
LATEX source is changed into .gif images by the imagen
script, which basically calls, LATEX, dvips,
ghostscript
and a few tools from the image processing package
netpbm.
To benefit from the full functionality of HEVEA, you need all
this software. However, HEVEA runs without them, but then you will
to manage to produce images by yourself.
The details are given in the README
file from the distribution.
Basically, HEVEA should be given a library
directory. The installation procedure stores the hevea.hva
and base style files in this directory.
There are two compilation modes, the opt mode selects the
native code Ocaml compiler ocamlopt, while the byte
mode selects the bytecode Ocaml compiler ocamlc.
In HEVEA case, ocamlopt produces code that is up to three
times as fast as the one produced by ocamlc.
Thus, default compilation mode is opt, however it may be the
case on some systems that only ocamlc is available.
Note that the hevea.sty file is simply copied to HEVEA
library directory. It remains users responsibility to
make it accessible to LATEX.
