# vflmkcaptex
# --- Generate vflibcap for TeX DVI drivers
#     (Especially, DVIware of the TeX-Guy Project)
#
# by Hirotsugu Kakugawa
# 
# 13 May 2001
# 12 Oct 2001  Fixed bugs. Thanks to James Hirschorn.
#              Changed to read modex.mf to obtain device resolution. 
# 21 Jul 2005  Enhanced searching "config.ps" and type 1 font files.
# 33 Jul 2005  Added -t1map option. Changed type1 mapping files used.
