--- This script will create three different config files from three tables
--- with values determined by the host and configuration options:
---
--- The table `config' contains key-value pairs to be written to the file
--- `config.h' which is included by sources files. Boolean values will
--- either #define or #undef the key with no associated values. String
--- values will be defined as quoted strings while any other value,
--- particularly numbers, will be defined unquoted.
---
--- The table `define' contains key-value pairs to be written to the file
--- `config.mk' which is included by the Makefile. Values are assigned to
--- their keys as they are, unquoted.
---
--- The table `export' contains key-value pairs to be written to the file
--- `config.sed' which is used by sed to perform search-and-replace on files
--- containing @REPLACE_ME@-style keywords. When used with sed, such
--- keyworded keys will be replaced by their values as they are, unquoted.

-This is NOT an autoconf-generated configure script, though it was written
-to be familiar by supporting many of the same options.
-
-Basic configuration:
- -h, --help display this help and exit
- --host=HOST cross-compile the program to run on HOST
-
- --prefix=DIR base directory to install programs to
- --bindir=DIR directory to install executables
- --datadir=DIR directory to install shared data files
- --mandir=DIR directory to install manual pages
-
- --disable-dependency-tracking speed up one-time builds (maybe)
- --disable-special-linking do not use direct dependency minimizer
- --enable-profile compile in gprof profiling instructions
-
-Program options:
- --enable-clock_gettime use a very accurate timing function
- --enable-debug compile in assertion checks and other debug helps
- --enable-double-precision use larger floating-point numbers
- --enable-hotload automatically reload modified game assets
- --enable-threads use threads for concurrency where appropriate
-
- --with-gtk use the gtk2 toolkit (overrides --with-qt4)
- --with-qt4 use the qt4 gui toolkit

--- of the form --enable-OPT= and --with-OPT= can be obtained with the
--- functions get_feature and get_package, respectively. Like
--- autoconf-generated scripts, passing --disable-OPT or --without-OPT is
--- equivalent to passing --enable-OPT=no and --without-OPT=no,
--- respectively. Values that are either yes or no are interpreted as
--- booleans. Any other values are interpreted as strings.
---
--- Definitions of the form KEY=VALUE are also supported. If passed, the
--- option parsing routine below will place these options in the global
--- namespace.
---
--- Finally, the options -h, --help, and --host are also supported, the
--- former two calling the show_help function and the latter setting the
--- host global variable.
