# This script creates (or regenerates) `configure` (as well as `aclocal.m4`
# file, `config.h.in` file, `Makefile.in` file, etc.) missing in the source
# repository.
#
# If you compile from a distribution tarball, you can skip this.  Otherwise,
# make sure that you have Autoconf, Automake and Libtool installed
# on your system, and that the corresponding "*.m4" files are visible
# to the `aclocal`.  The latter can be achieved by using packages shipped by
# your OS, or by installing custom versions of all four packages to the same
# prefix.  Otherwise, you may need to invoke `autoreconf` with the appropriate
# `-I` options to locate the required "*.m4" files.

# Install `libtool.m4` and `ltmain.sh` files in the build tree.  This command
# is needed if `autoreconf` and `libtoolize` are available from the different
# directories.
# Note: `libtoolize` might be missing on some platforms.
