graphics. If passed no arguments, this will list all the files in the

/* We handle the command-line switches here because fetching the number of
columns in the window using, say, tput, doesn't seem to work right within
a Java process. We instead have an external script at ~/bin/lsim that
sets the -c flag.
The bash file "lsim" that sets the number of columns looks like (adjust
paths for your system):
#!/bin/bash
cols=$(tput cols)
frink /home/eliasen/prog/frink/samples/lsim.frink -c $cols "$@"
