configure

#!/bin/sh

#  This is not a real autoconf configure script.
#  I will not ship a configure script that is larger than
#    the generated linux_logo executable.
#  This is a simple shell script that gathers the info linux_logo
#    needs, and should be compatible enough.
#  Tested on Linux, Irix, Solaris and FreeBSD
