# A script to reconfigure autotools for h5tuner.  This script is a 
# modification of the autogen.sh script found in HDF5, and differs 
# mainly in that it runs autoreconf instead of running aclocal,
# autoheader, automake and autoconf in order.  This may or may not change.
#
# IMPORTANT OS X NOTE
#
# If you are using OS X, you will probably not have the autotools
# installed, even if you have the Xcode command-line tools.
#
# The easiest way to fix this is to install everything via Homebrew:
#
#   http://brew.sh/
#
# After you install the base packages, install autoconf, automake,
# and libtool.
#
#   brew install autoconf
#   brew install automake
#   brew install libtool
#
# This only takes a few minutes. Note that libtool and libtoolize will
# be glibtool and glibtoolize so as not to conflict with Apple's non-gnu
# tools. This autogen.sh script handles this for you.
#
# END IMPORTANT OS X NOTE
#
# If you want to use a particular version of the autotools, the paths
# to each tool can be overridden using the following environment
# variables:
#
#   H5TUNER_ACLOCAL
#   H5TUNER_AUTOHEADER
#   H5TUNER_AUTOMAKE
#   H5TUNER_AUTOCONF
#   H5TUNER_LIBTOOL
#   H5TUNER_M4
#
# Note that aclocal will attempt to include libtool's share/aclocal
# directory.
#
# This script takes two potential options:
#
#
# -p
#
# When this is selected, the autotools versions are set to the paths
# and versions used by The HDF Group to produce the released versions
# of the library.
#
# NOTE: This is probably temporary. Once we update our dev machines
# to have recent versions of the autotools this option will probably
# be removed.
#
# -v
#
# This emits some extra information, mainly tool versions.
