-# Local Autoconf Macros
-#=========================================================================
-# This file contains the macros for the Modular C++ Build System and
-# additional autoconf macros which developers can use in their
-# configure.ac scripts. Please read the documentation in
-# 'mcppbs-doc.txt' for more details on how the Modular C++ Build System
-# works. The documenation for each macro should include information
-# about the author, date, and copyright.
-
-#-------------------------------------------------------------------------
-# MCPPBS_PROG_INSTALL
-#-------------------------------------------------------------------------
-# This macro will add an --enable-stow command line option to the
-# configure script. When enabled, this macro will first check to see if
-# the stow program is available and if so it will set the $stow shell
-# variable to the binary name and the $enable_stow shell variable to
-# "yes". These variables can be used in a makefile to conditionally use
-# stow for installation.
-#
-# This macro uses two environment variables to help setup default stow
-# locations. The $STOW_PREFIX is used for stowing native built packages.
-# The packages are staged in $STOW_PREFIX/pkgs and then symlinks are
-# created from within $STOW_PREFIX into the pkgs subdirectory. If you
-# only do native builds then this is all you need to set. If you don't
-# set $STOW_PREFIX then the default is just the normal default prefix
-# which is almost always /usr/local.
-#
-# For non-native builds we probably want to install the packages in a
-# different location which includes the host architecture name as part
-# of the prefix. For these kind of builds, we can specify the $STOW_ROOT
-# environment variable and the effective prefix will be
-# $STOW_ROOT/${host_alias} where ${host_alias} is specified on the
-# configure command line with "--host".
-#
-# Here is an example setup:
-#
-# STOW_ROOT="$HOME/install"
-# STOW_ARCH="i386-macosx10.4"
-# STOW_PREFIX="${STOW_ROOT}/${STOW_ARCH}"

-# MCPPBS_SUBPROJECTS([ sproj1, sproj2, ... ])
-#-------------------------------------------------------------------------
-# The developer should call this macro with a list of the subprojects
-# which make up this project. One should order the list such that any
-# given subproject only depends on subprojects listed before it. The
-# subproject names can also include an * suffix which indicates that
-# this is an optional subproject. Optional subprojects are only included
-# as part of the project build if enabled on the configure command line
-# with a --enable-<subproject> flag. The user can also specify that all
-# optional subprojects should be included in the build with the
-# --enable-optional-subprojects flag.
-#
-# Subproject names can also include a ** suffix which indicates that it
-# is an optional subproject, but there is a group with the same name.
-# Thus the --enable-<sproj> command line option will enable not just the
-# subproject sproj but all of the subprojects which are in the group.
-# There is no error checking to make sure that if you use the ** suffix
-# you actually define a group so be careful.
-#
-# Both required and optional subprojects should have a 'subproject.ac'
-# file. The script's filename should be the abbreivated subproject name
-# (assuming the subproject name is sproj then we would use 'sproj.ac')
-# The MCPPBS_SUBPROJECTS macro includes the 'subproject.ac' files for
-# enabled subprojects. Whitespace and newlines are allowed within the
-# list.
