/**
 * @defgroup Start Getting Started

 *
 * To write an Elementary app, you can get started with the following:
 *
 * @code
 * #include <Elementary.h>
 * #ifndef ELM_LIB_QUICKLAUNCH
 * EAPI int
 * elm_main(int argc, char **argv)
 * {
 *    // create window(s) here and do any application init
 *    elm_run(); // run main loop
 *    elm_shutdown(); // after mainloop finishes running, shutdown
 *    return 0; // exit 0 for exit code
 * }
 * #endif
 * ELM_MAIN()
 * @endcode
 *
 * To take full advantage of the quicklaunch architecture for launching
 * processes as quickly as possible (saving time at startup time like
 * connecting to X11, loading and linking shared libraries) you may want to
 * use the following configure.in/configure.ac and Makefile.am and autogen.sh
 * script to generate your files. It is assumed your application uses the
 * main.c file for its code.

@endverbatim
 *
 * To gnerate all the things needed to bootstrap just run:
 *
@verbatim
./autogen.sh
@endverbatim
 *
 * This will generate Makefile.in's, the confgure script and everything else.
 * After this it works like all normal autotools projects:
@verbatim
./configure
make
sudo make install
@endverbatim
 *
 * Note sudo was assumed to get root permissions, as this would install in
 * /usr/local which is system-owned. Use any way you like to gain root, or
 * specify a different prefix with configure:
 *
@verbatim
./confiugre --prefix=$HOME/mysoftware
@endverbatim
 *
 * Also remember that autotools buys you some useful commands like:
@verbatim
make uninstall
@endverbatim
 *
 * This uninstalls the software after it was installed with "make install".
 * It is very useful to clear up what you built if you wish to clean the
 * system.
 *
@verbatim
make distcheck
@endverbatim
 *
 * This firstly checks if your build tree is "clean" and ready for
 * distribution. It also builds a tarball (myapp-0.0.0.tar.gz) that is
 * ready to upload and distribute to the world, that contains the generated
 * Makefile.in's and configure script. The users do not need to run
 * autogen.sh - just configure and on. They don't need autotools installed.
 * This tarball also builds cleanly, has all the sources it needs to build
 * included (that is sources for your application, not libraries it depends
 * on like Elementary). It builds cleanly in a buildroot and does not
 * contain any files that are temporarily generated like binaries and other
 * build-generated files, so the tarball is clean, and no need to worry
 * about cleaning up your tree before packaging.
 *
@verbatim
make clean
@endverbatim
 *
 * This cleans up all build files (binaries, objects etc.) from the tree.
 *
@verbatim
make distclean
@endverbatim
 *
 * This cleans out all files from the build and from configure's output too.
 *
@verbatim
make maintainer-clean
@endverbatim
 *
 * This deletes all the files autogen.sh will produce so the tree is clean
 * to be put into a revision-control system (like CVS, SVN or GIT for example).
 *
 * The above will build a library - libmyapp.so and install in the target
 * library directory (default is /usr/local/lib). You will also get a
 * myapp.a and myapp.la - these are useless and can be deleted. Libtool likes
 * to generate these all the time. You will also get a binary in the target
 * binary directory (default is /usr/local/bin). This is a "debug binary".
 * This will run and dlopen() the myapp.so and then jump to it's elm_main
 * function. This allows for easy debugging with GDB and Valgrind. When you
 * are ready to go to production do the following:
 *
 * 1. delete the myapp binary. i.e. rm /usr/local/bin/myapp
 *
 * 2. symlink the myapp binary to elementary_run (supplied by elementary).
 * i.e. ln -s elmentary_run /usr/local/bin/myapp
 *
 * 3. run elementary_quicklaunch as part of your graphical login session and
 * keep it running.
 *
 * This will man elementary_quicklaunch does pre-initialization before the
 * application needs to be run, saving the effort at the time the application
 * is needed, thus speeding up the time it takes to appear.
 *
 * If you don't want to use the quicklaunch infrastructure (which is
 * optional), you can execute the old fashioned way by just running the
 * myapp binary loader than will load the myapp.so for you, or you can
 * remove the split-file binary and put it into one binary as things always
 * have been with the following configure.in/configure.ac and Makfile.am
 * files:
 *
 * configure.in/configure.ac:
