# SYNOPSIS
#
#   AC_PROG_MODPROBE
#
# DESCRIPTION
#
#   This macro searches for a modprobe command, such as can be found on
#   Linux systems with loadable kernel module support. PATH is checked
#   first, then the default location(s).
#
#   This is one of several autoconf macros intended to assist in
#   configuring and installing loadable kernel modules.
