+#!/bin/sh
+#
+# Converts from a pair of Postscript font files (file.pfb and
+# file.afm) to an egg file and associated texture map that is suitable
+# for using with the TextNode class in Panda to render text in the
+# world.
+#
+# Note that the pfb file is a Postscript font file, not to be confused
+# with a Performer scene graph file (which also used the .pfb
+# extension).  This script has nothing to do with Performer.
+#
+# Both a pfb file and an afm file ("Adobe Font Metrics") must be
+# supplied.  Typically, Postscript fonts are shipped to Windows with a
+# pfm file ("Printer Font Metrics") instead of an afm file.  If this
+# is the case, you must use a utility like CrossFont to convert the
+# pfm to afm format.  (Look to http://www.asy.com/ for CrossFont, or
+# see http://www.sketchpad.net/fonts1.htm for a treatise on the
+# subject.)
+#
+# This script takes advantage of afm2tfm and ps2pk, which I believe
+# are typically shipped with TeX.
+#
+#
+# Usage:
+# 
+#   pfb2egg [opts] file.pfb file.egg -- [mkfont-opts]
+#
+# Options that control the behavior of this script must appear first.
+# The extra options options following the first two parameters are passed
+# unchanged to egg-mkfont.
+#
+# The afm file is assumed to be the same name as the pfb file, with
+# pfb replaced by afm.
+#
+# Local options:
+#
+#   -d dpi
+#       Specify the resolution at which to rasterize the font before
+#       converting it.  This affects the size of the generated texture
+#       image and, in turn, the clarity of the resulting font.  The
+#       default is 720, which generally seems to be a good ratio.
+#
+#   -p pointsize
+#       Specify the pointsize at which to convert the font.  This doesn't
+#       make a whole lot of difference to its appearance other than
+#       scaling the dpi value, above, unless the font has a different
+#       appearance at smaller point sizes (some fonts include hints to
+#       change the way they are rendered at small point sizes).  The
+#       default is 10.
+#
+# See egg-mkfont -h for a description of the additional options.
