-# This script creates virtual subfonts in Unicode encoding for Wadalab
-# subfonts. It can merge a JIS X 0208 and JIS X 0212 family into a single
-# set of Unicode subfonts.
-#
-# As prerequisites, it needs the files `JIS0208.TXT' and `JIS0212.TXT' from
-# the `OBSOLETE' directory in the `MAPPINGS' tree on ftp.unicode.org. It
-# also needs the file `DNP.sfd' which gives the relationship between JIS X
-# 0208 (and JIS X 0212) in EUC encoding and wadalab's DNP font encoding.
-# The program `vptovf' must be available (and in the path).
-#
-# Call the script as
-#
-# perl makeuniwada.pl namestem1 [namestem2] uni_namestem
-#
-# `namestem1' is the font in JIS X 0208 encoding. The optional `namestem2'
-# argument is the font in JIS X 0212, and `uni_namestem' holds the prefix
-# for the Unicode subfonts. `makeuniwada.pl' reads all AFM files from the
-# given wadalab font families.
-#
-# Example:
-#
-# perl makeuniwada.pl dmj mc2j udmj
-#
-# This call mixes the mincho-0-12 (dmj) with mincho-1-8 (mc2j) families.
