+# SYNOPSIS
+#
+#   AX_PROG_LUA[([MINIMUM-VERSION], [TOO-BIG-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#   AX_LUA_HEADERS[([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#   AX_LUA_LIBS[([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#   AX_LUA_READLINE[([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])]
+#
+# DESCRIPTION
+#
+#   Detect a Lua interpreter, optionally specifying a minimum and maximum
+#   version number. Set up important Lua paths, such as the directories in
+#   which to install scripts and modules (shared libraries).
+#
+#   Also detect Lua headers and libraries. The Lua version contained in the
+#   header is checked to match the Lua interpreter version exactly. When
+#   searching for Lua libraries, the version number is used as a suffix.
+#   This is done with the goal of supporting multiple Lua installs (5.1,
+#   5.2, and 5.3 side-by-side).
+#
+#   A note on compatibility with previous versions: This file has been
+#   mostly rewritten for serial 18. Most developers should be able to use
+#   these macros without needing to modify configure.ac. Care has been taken
+#   to preserve each macro's behavior, but there are some differences:
+#
+#   1) AX_WITH_LUA is deprecated; it now expands to the exact same thing as
+#   AX_PROG_LUA with no arguments.
+#
+#   2) AX_LUA_HEADERS now checks that the version number defined in lua.h
+#   matches the interpreter version. AX_LUA_HEADERS_VERSION is therefore
+#   unnecessary, so it is deprecated and does not expand to anything.
+#
+#   3) The configure flag --with-lua-suffix no longer exists; the user
+#   should instead specify the LUA precious variable on the command line.
+#   See the AX_PROG_LUA description for details.
+#
+#   Please read the macro descriptions below for more information.
+#
+#   This file was inspired by Andrew Dalke's and James Henstridge's
+#   python.m4 and Tom Payne's, Matthieu Moy's, and Reuben Thomas's ax_lua.m4
+#   (serial 17). Basically, this file is a mash-up of those two files. I
+#   like to think it combines the best of the two!
+#
+#   AX_PROG_LUA: Search for the Lua interpreter, and set up important Lua
+#   paths. Adds precious variable LUA, which may contain the path of the Lua
+#   interpreter. If LUA is blank, the user's path is searched for an
+#   suitable interpreter.
+#
+#   If MINIMUM-VERSION is supplied, then only Lua interpreters with a
+#   version number greater or equal to MINIMUM-VERSION will be accepted. If
+#   TOO-BIG-VERSION is also supplied, then only Lua interpreters with a
+#   version number greater or equal to MINIMUM-VERSION and less than
+#   TOO-BIG-VERSION will be accepted.
+#
+#   The Lua version number, LUA_VERSION, is found from the interpreter, and
+#   substituted. LUA_PLATFORM is also found, but not currently supported (no
+#   standard representation).
+#
+#   Finally, the macro finds four paths:
+#
+#     luadir             Directory to install Lua scripts.
+#     pkgluadir          $luadir/$PACKAGE
+#     luaexecdir         Directory to install Lua modules.
+#     pkgluaexecdir      $luaexecdir/$PACKAGE
+#
+#   These paths are found based on $prefix, $exec_prefix, Lua's
+#   package.path, and package.cpath. The first path of package.path
+#   beginning with $prefix is selected as luadir. The first path of
+#   package.cpath beginning with $exec_prefix is used as luaexecdir. This
+#   should work on all reasonable Lua installations. If a path cannot be
+#   determined, a default path is used. Of course, the user can override
+#   these later when invoking make.
+#
+#     luadir             Default: $prefix/share/lua/$LUA_VERSION
+#     luaexecdir         Default: $exec_prefix/lib/lua/$LUA_VERSION
+#
+#   These directories can be used by Automake as install destinations. The
+#   variable name minus 'dir' needs to be used as a prefix to the
+#   appropriate Automake primary, e.g. lua_SCRIPS or luaexec_LIBRARIES.
+#
+#   If an acceptable Lua interpreter is found, then ACTION-IF-FOUND is
+#   performed, otherwise ACTION-IF-NOT-FOUND is preformed. If ACTION-IF-NOT-
+#   FOUND is blank, then it will default to printing an error. To prevent
+#   the default behavior, give ':' as an action.
+#
+#   AX_LUA_HEADERS: Search for Lua headers. Requires that AX_PROG_LUA be
+#   expanded before this macro. Adds precious variable LUA_INCLUDE, which
+#   may contain Lua specific include flags, e.g. -I/usr/include/lua5.1. If
+#   LUA_INCLUDE is blank, then this macro will attempt to find suitable
+#   flags.
+#
+#   LUA_INCLUDE can be used by Automake to compile Lua modules or
+#   executables with embedded interpreters. The *_CPPFLAGS variables should
+#   be used for this purpose, e.g. myprog_CPPFLAGS = $(LUA_INCLUDE).
+#
+#   This macro searches for the header lua.h (and others). The search is
+#   performed with a combination of CPPFLAGS, CPATH, etc, and LUA_INCLUDE.
+#   If the search is unsuccessful, then some common directories are tried.
+#   If the headers are then found, then LUA_INCLUDE is set accordingly.
+#
+#   The paths automatically searched are:
+#
+#     * /usr/include/luaX.Y
+#     * /usr/include/lua/X.Y
+#     * /usr/include/luaXY
+#     * /usr/local/include/luaX.Y
+#     * /usr/local/include/lua-X.Y
+#     * /usr/local/include/lua/X.Y
+#     * /usr/local/include/luaXY
+#
+#   (Where X.Y is the Lua version number, e.g. 5.1.)
+#
+#   The Lua version number found in the headers is always checked to match
+#   the Lua interpreter's version number. Lua headers with mismatched
+#   version numbers are not accepted.
+#
+#   If headers are found, then ACTION-IF-FOUND is performed, otherwise
+#   ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then
+#   it will default to printing an error. To prevent the default behavior,
+#   set the action to ':'.
+#
+#   AX_LUA_LIBS: Search for Lua libraries. Requires that AX_PROG_LUA be
+#   expanded before this macro. Adds precious variable LUA_LIB, which may
+#   contain Lua specific linker flags, e.g. -llua5.1. If LUA_LIB is blank,
+#   then this macro will attempt to find suitable flags.
+#
+#   LUA_LIB can be used by Automake to link Lua modules or executables with
+#   embedded interpreters. The *_LIBADD and *_LDADD variables should be used
+#   for this purpose, e.g. mymod_LIBADD = $(LUA_LIB).
+#
+#   This macro searches for the Lua library. More technically, it searches
+#   for a library containing the function lua_load. The search is performed
+#   with a combination of LIBS, LIBRARY_PATH, and LUA_LIB.
+#
+#   If the search determines that some linker flags are missing, then those
+#   flags will be added to LUA_LIB.
+#
+#   If libraries are found, then ACTION-IF-FOUND is performed, otherwise
+#   ACTION-IF-NOT-FOUND is performed. If ACTION-IF-NOT-FOUND is blank, then
+#   it will default to printing an error. To prevent the default behavior,
+#   set the action to ':'.
+#
+#   AX_LUA_READLINE: Search for readline headers and libraries. Requires the
+#   AX_LIB_READLINE macro, which is provided by ax_lib_readline.m4 from the
+#   Autoconf Archive.
+#
+#   If a readline compatible library is found, then ACTION-IF-FOUND is
+#   performed, otherwise ACTION-IF-NOT-FOUND is performed.

+# SYNOPSIS
+#
+#   AX_REQUIRE_DEFINED(MACRO)
+#
+# DESCRIPTION
+#
+#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
+#   been defined and thus are available for use.  This avoids random issues
+#   where a macro isn't expanded.  Instead the configure script emits a
+#   non-fatal:
+#
+#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
+#
+#   It's like AC_REQUIRE except it doesn't expand the required macro.
+#
+#   Here's an example:
+#
+#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])
