# Simple font generator for homedecor signs mod
# By Vanessa Ezekowitz
#
# License: WTFPL
# Usage:
#
# signs-chargen.sh fontname fontheight [top-excess bottom-excess left-excess right-excess]
#
# font is the standard X11 font spec, in quotes, such as:
# "-*-helvetica-*-r-*-*-12-*-*-*-*-*-*-*"
#
# Note that top+bottom excess can easily exceed the specified font size. The excess values
# must all be specified if any are.
