Hi, Geoffrey.
I'm unsure how to go about getting some fixes to
http://ctan.tug.org/tex-archive/dviware/dtl/
into CTAN. As you're the author and as you have a pointer to LyX on your TeX
page, perhaps you're interested?
The attached patch does a number of things:
* it enables the Makefile to work out of the box on both *nix and on Windows
under either the MSys or Cygwin environments.
* it fixes the man2ps Makefile target
* it fixes man2ps itself to not use hard-coded paths to groff or dpost
* it enables dt2dv.c to handle .dvi files containing strings longer than 1024
chars. Such files are commonly generated by the PSTricks package.
In addition, note that you have some spurious whitespace at the end of lines
in the .doc files ;-)
We've been using the dtl package in the Windows build of LyX for a year or so
now without any problems. It enables us to manipulate the file name strings
output by graphix.sty so that file names containing spaces can be understood
by Yap. See
http://www.lyx.org/trac/browser/lyx-devel/trunk/lib/scripts/clean_dvi.py
Sure this is a kludge around a broken graphix.sty, but the whole "file name
with spaces" thing is a mess in TeX ATM and dtl has enabled us to create an
engineering solution to the problem. It's been just great! ;-)
Kind regards,
Angus
