The integer is the number of separate jobs to +# allow. If 'yes' is given, then the is assumed to be one more than the +# number of CPUs (determined through AX_COUNT_CPUS). If the value of no is +# given, then the jobserver is disabled. The default value is given by the +# first argument of the macro, or 'yes' if the argument is omitted. +# +# This macro makes use of AX_AM_MACROS, so you must add the following line +# +# @INC_AMINCLUDE@ +# +# to your Makefile.am files. +# +# LICENSE +# +# Copyright (c) 2008 Michael Paul Bailey <jinxidoru@byu.net> +# +# Copying and distribution of this file, with or without modification, are +# permitted in any medium without royalty provided the copyright notice +# and this notice are preserved.
