   2 #@ make-afmtodit-tables -- script for creating the `unicode_decomposed'
   3 #@                         and `AGL_to_unicode' tables
   4 #@ Synopsis:
   5 #@   make-afmtodit-tables \
   6 #@     UnicodeData.txt version-string glyphlist.txt > afmtodit.in
   7 #@
   8 #@ `UnicodeData.txt' is the central database file from the Unicode standard.
   9 #@ Unfortunately, it doesn't contain a version number which must be thus
  10 #@ provided manually as an additional parameter.
  11 #@ `glyphlist.txt' holds the Adobe Glyph List (AGL).
  12 #@ This program needs a C preprocessor.
  13 #@ TODO remove in favour of S-CText
