+# how the Modular C++ Build System works. For most projects, a developer
+# will not need to make any changes to this makefile. The key targets
+# are as follows:
+#
+# - default : build all libraries and programs
+# - check : build and run all unit tests
+# - install : install headers, project library, and some programs
+# - clean : remove all generated content (except autoconf files)
+# - dist : make a source tarball
+# - distcheck : make a source tarball, untar it, check it, clean it
+# - distclean : remove everything
+#

+Modular C++ Build System Template
+==========================================================================
+# Author : Christopher Batten
+# Date : September 24, 2008
+# Version : (under version control)
+
+This is a template for the Modular C++ Build System. Please refer to the
+following documentation for more information on the build system:
+
+ - 'mcppbs-uguide.txt' : Modular C++ Build System User Guide
+ - 'utst/utst-uguide.txt' : Unit Testing Framework User Guide
+ - 'style-guide.txt' : C++ Coding Style Guide
+
+Developers should eventually replace this 'README' file with information
+on their new project. It is recommended that the new 'README' file keep
+pointers to the above documentation so that end-users can learn about
+the build system. You may also want to keep the version information
+around so that you know what version of the build system you are using.
+
+--------------------------------------------------------------------------
+Template Instantiation
+--------------------------------------------------------------------------
+
+ - Update project metadata (name, maintainer, etc) in 'configure.ac'
+ - Run 'autoconf && autoheader' in project's root directory
+ - Add subprojects and update the list in 'configure.ac'
+
+--------------------------------------------------------------------------
+Build Steps
+--------------------------------------------------------------------------
+
+ % mkdir build
+ % cd build

+# 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:

+# 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

+\`configure' configures RISC-V Proxy Kernel ? to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ STOW_ROOT Root for non-native stow-based installs
+ STOW_PREFIX Prefix for stow-based installs
+ CPP C preprocessor
+

+# This script will create a version string by querying a version control
+# system. The string is appropriate for use in installations and
+# distributions. Currently this script assumes we are using git as our
+# version control system but it would be possible to check and see if we
+# are using an alternative version control system and create a version
+# string appropriately.
+#
+# The script uses git describe plus a few other git commands to create a
+# version strings in the following format:
+#
+# X.Y[-Z-gN][-dirty]
+#
+# where X is the major release, Y is the minor release, Z is the number
+# of commits since the X.Y release, N is an eight digit abbreviated SHA
+# hash of the most recent commit and the dirty suffix is appended when
+# the working directory used to create the installation or distribution
+# is not a pristine checkout. Here are some example version strings:
+#
+# 0.0 : initial import
+# 0.0-3-g99ef6933 : 3rd commit since initial import (N=99ef6933)
+# 1.0 : release 1.0
+# 1.1-12-g3487ab12 : 12th commit since release 1.1 (N=3487ab12)
+# 1.1-12-g3487ab12-dirty : 12th commit since release 1.1 (N=3487ab12)
+#
+# The last example is from a dirty working directory. To find the last
+# release, the script looks for the last tag (does not need to be an
+# annotated tag, but probably should be) which matches the format rel-*.
+# If there is no such tag in the history, then the script uses 0.0 as
+# the release number and counts the total number of commits since the
+# original import for the commit count.
+#
+# If the current directory is not within the working directory, then the
+# path to the source directory should be supplied on the command line.
