#
# This script adds AGL compliant glyph names to fonts from the HLaTeX
# package version 0.97 or newer. Note that only glyphs actually used in the
# (virtual) HLaTeX subfonts get new names; additionally, the used glyph
# shapes in the HLaTeX fonts aren't always correct -- consider this script
# as an auxiliary means, not a definitive solution. At least the Hangul and
# Hanja shapes are correct.
#
# As prerequisites, it needs the programs `t1asm' and `t1disasm' (from the
# t1utils package) and `vftovp' which must be in the path. The subfont
# definition file `UKS-HLaTeX.sfd' (from the ttf2pk package) and the file
#
# http://partners.adobe.com/public/developer/en/opentype/aglfn13.txt
#
# are necessary also.
#
# Call the script as
#
# perl hlatex2agl.pl virtual-namestem real-namestem sfd-file
#
# `virtual-namestem' specifies the name stem of the virtual subfonts
# directly used by LaTeX; both the VF and TFM files are needed.
# `real-namestem' gives the name stem of the real subfonts used by the
# virtual fonts; TFM, AFM, and PFB files are needed.
#
# Example:
#
# perl hlatex2agl.pl wmj umj UKS-HLaTeX.sfd
