# ===========================================================================
#
# SYNOPSIS
#
# AC_COND_WITH_LEVEL(PACKAGE [,DEFAULT [,YESLEVEL]])
#
# DESCRIPTION
#
# Actually used after an AC_ARG_WITH(PKG,...) option-directive, where
# AC_ARG_WITH is a part of the standard autoconf to define a `configure`
# --with-PKG option.
#
# This macros works almost like AC_COND_WITH(PACKAGE [,DEFAULT]), but the
# definition is set to a numeric value. The level of a simple "yes" is
# given (or assumed "2" if absent), otherwise the level can be given in
# mnemonic names, being:
#
# 1 = some
# 2 = many
# 3 = all
# 4 = extra
# 5 = extrasome more
# 6 = extramany muchmore much
# 7 = super everything
# 8 = ultra experimental
# 9 = insane
#
# this macro is most handily it making Makefile.in/Makefile.am that have a
# set of with-level declarations, espcially optimization-levels
#
# the $withval shell-variable is set for further examination (it carries
# the numeric value of the various mnemonics above)
