# Lists all fonts and control files in figlet's default font directory.
# Replaces "figlet -F", which was removed from figlet version 2.1.
#
# Usage: figlist [ -d directory ]
#
# If this script doesn't work on your system, try
# figlet -F        (figlet 2.0)
# ls `figlet -I2`  (figlet 2.1 or later)
#
# Or, if the problem is only that your system doesn't have the "wc" (word
# count) program, put a "#" at the beginning of the two lines containing
# "wc", i.e., the lines beginning "NUMFONTS=" and "NUMCONTROL=".
