prepare

#! /bin/sh --
# Small shell script to prepare the gnuplot sources when
# checked out from CVS.

# Note that autoconf 2.52 or newer is required; automake versions older than
# 1.7 might not work
# April 2012 - The AC_HEADER_STDBOOL macro is unreliable in autoconf versions < 2.68

# allow importing from the environment (mainly for FreeBSD; use
# "AUTOCONF=autoconf259 ... ./prepare")
