# A script to reconfigure autotools for HDF5, and to recreate other
# generated files specifc to HDF5.
#
# 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
# bison version you have installed may also have a bug that makes
# it unable to process our input files.
# 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,
# libtool, and flex/bison.
# and libtool.
#
#   brew install autoconf
#   brew install automake
#   brew install libtool
#   brew install flex
#   brew install bison
#
# 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:
#
#   HDF5_ACLOCAL
#   HDF5_AUTOHEADER
#   HDF5_AUTOMAKE
#   HDF5_AUTOCONF
#   HDF5_LIBTOOL
#   HDF5_M4
#   HDF5_FLEX
#   HDF5_BISON
#
# 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
