# A script to reconfigure the Autotools for HDF5, and to recreate other
# generated files specific 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 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
#
# END IMPORTANT OS X NOTE
