Subject: Hyperlinks for ITEX PostScript (hl4ip version 1.36) available

I have released my Hyperlinks for ITEX PostScript postprocessor
hl4ip as open source software under the GNU General Public License.

What is hl4ip?

Using the ITEX-generated and as input hl4ip outputs the
PostScript code contained in plus additional bookmarks and
hyperlinks for TTCN identifiers (via the PostScript pdfmark operator)
which become activate when the output of hl4ip is postprocessed by
e.g. ps2pdf(1) from the Ghostscript distribution or the Acrobat
Distiller from Adobe Systems.

Browsing and navigation in a hl4ip-enabled PDF file is therefore much
easier compared to a PDF file generated from the regular PostScript output.

hl4ip is implemented in Awk and is available from

Quick installation instructions:

mkdir ~/hl4ip
cd ~/hl4ip
gzip -dc hl4ip.tgz | tar xvf -
## Check whether BINDIR, MANDIR, AWK & INSTALL in Makefile need adapting
## Use
make install
## for a full installation or
make hl4ip
## for a quick check of hl4ip capabilities and then
## (if you have a working Ghostscript installation)
hl4ip /path/to/ /path/to/ | ps2pdf /dev/stdin ATS.pdf

Please note that hl4ip acts as a postprocessor on the regular
PostScript output from ITEX. The following limitations therefore apply:
* The addition of hyperlinks is based on a textual analysis
of the PostScript input instead of using the AST which
might lead to some wrong hyperlinks being added.
* The heuristics used to find identifiers may not work in some
special cases or with non-A4 paper formats.
* It might not work when using the PostScript output produced by
the Windows version or newer Unix versions with changed output
