# A script to reconfigure autotools for H4H5TOOLS, and to recreate other
# generated files specifc to H4H5TOOLS.
# If the paths of the autotools are not specified by the user, they
# are hardcoded to point to their locations on H4H5TOOLS Linux machines.
# Users can specify the locations of the autotools with the following
# variables:
# AUTOCONF, AUTOMAKE, ACLOCAL, AUTOHEADER should be the path to the
# corresponding tools.
# Be very careful when specifying these tools manually!  There are a lot
# of versions that can get confused (not even counting the m4 utility)!

# H4H5TOOLS currently uses the following versions of the autotools:
AUTOCONF_VERSION="autoconf (GNU Autoconf) 2.69"
AUTOMAKE_VERSION="automake (GNU automake) 1.14.1"
ACLOCAL_VERSION="aclocal (GNU automake) 1.14.1"
M4_VERSION="m4 (GNU M4) 1.4.17"

#
# When upgrading automake's version, don't forget to also update its
# helper utilities, especially depcomp.


# If paths to autotools are not specified by the user, assume tools are
# running on jam in /mnt/hdf/packages and set paths accordingly.
