+# This is a simple script which is meant to help developers
+# better deal with the GNU autotools, specifically:
+#
+#   aclocal
+#   libtoolize
+#   autoconf
+#   autoheader
+#   automake
+#
+# The whole thing is quite complex...
+#
+# The idea is to run this collection of tools on a single platform,
+# typically the main development platform, running a recent version of
+# autoconf. In theory, if we had these tools on each platform where we
+# ever expected to port the software, we would never need to checkin
+# more than a few autotools configuration files. However, the whole
+# idea is to generate a configure script and associated files in a way
+# that is portable across platforms, so we *have* to check in a whole
+# bunch of files generated by all these tools.
+
+# The real source files are:
+#
+# acinclude.m4 (used by aclocal)
+# configure.ac (main autoconf file)
+# Makefile.am, */Makefile.am (automake config files)
+#
+# All the rest is auto-generated.

+# Prevent any errors that might result from failing to properly invoke
+# `libtoolize` or `glibtoolize,` whichever is present on your system,
+# from occurring by testing for its existence and capturing the absolute path to
+# its location for caching purposes prior to using it later on in 'Step 2:'

+#             files in config (config.guess, config.sub, depcomp,
+#             install-sh, missing, mkinstalldirs) plus COPYING and
+#             INSTALL from:

+#             . src/Makefile.am
