# This is the xdvi wrapper script for Debian, based on Thomas Esser's
# teTeX version 0.2.
# Debian version: Copyright Julian Gilbey, 2002. Lots of modifications
# by Chung-chieh Shan <ken@digitas.harvard.edu>.
# Also by TSUCHIYA Masatoshi <tsuchiya@pine.kuee.kyoto-u.ac.jp>.
# Original version: Copyright Thomas Esser, 1998.
# Permission to distribute this software is given under the terms of
# the GNU general public license version 2 or later.
# Thomas writes:
# This script sets some environment variables to make sure that xdvi's
# resource file in $XDVIINPUTS/xdvi is read by xdvi.bin.
# Special care was taken to make this work for old R3, too. Therefore,
# we need to modify XAPPLRESDIR. If you are running R4 or later, you
# can set XUSERFILESEARCHPATH for user specific application default
# files. You cannot use XAPPLRESDIR for user specific application default
# files.
# Julian writes:
# This has been rewritten in Perl so that we can mangle the arguments
# to handled gzipped dvi files, which not have errors if there are
# spaces in some arguments. XAPPLRESDIR is no longer modified.
# Stephen Gildea writes:
# Debian distributes X11R6, therefore this script should not clobber
# XAPPLRESDIR, which is for user customizations.
