/**
* @page Start Getting Started
*
* To write an Elementary app, you can get started with the following:
*
* @code
* #include <Elementary.h>
* EAPI_MAIN 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
* }
* ELM_MAIN()
* @endcode
*
* To use autotools (which helps in many ways in the long run, like being able
* to immediately create releases of your software directly from your tree
* and ensure everything needed to build it is there) you need a
* configure.ac, Makefile.am, and autogen.sh file.
*
* configure.ac:
*
* @code
* AC_INIT(myapp, 0.0.0, myname@mydomain.com)
* AC_PREREQ(2.52)
* AC_CONFIG_SRCDIR(configure.ac)
* AM_CONFIG_HEADER(config.h)
* AC_PROG_CC
* AM_INIT_AUTOMAKE(1.6 dist-bzip2)
* PKG_CHECK_MODULES([ELEMENTARY], elementary)
* AC_OUTPUT(Makefile)
* @endcode
*
* Makefile.am:
*
* @code
* AUTOMAKE_OPTIONS = 1.4 foreign
* MAINTAINERCLEANFILES = Makefile.in aclocal.m4 config.h.in configure depcomp install-sh missing
*
* INCLUDES = -I$(top_srcdir)
*
* bin_PROGRAMS = myapp
*
* myapp_SOURCES = main.c
* myapp_LDADD = @ELEMENTARY_LIBS@
* myapp_CFLAGS = @ELEMENTARY_CFLAGS@
* @endcode
*
* autogen.sh:
*
* @code
*#!/bin/sh
* echo "Running aclocal..." ; aclocal $ACLOCAL_FLAGS || exit 1
* echo "Running autoheader..." ; autoheader || exit 1
* echo "Running autoconf..." ; autoconf || exit 1
* echo "Running automake..." ; automake --add-missing --copy --gnu || exit 1
* ./configure "$@"
* @endcode
*
* To generate all the things needed to bootstrap just run:
*
* @code
* ./autogen.sh
* @endcode
*
* This generates Makefile.in's, the configure script and everything else.
* After this it works like all normal autotools projects:
* @code
* ./configure
* make
* sudo make install
* @endcode
*
* Note sudo is assumed to get root permissions, as this would install in
* /usr/local which is system-owned. Use it any way you like to gain root, or
* specify a different prefix with configure:
*
* @code
* ./configure --prefix=$HOME/mysoftware
* @endcode
*
* Also remember that autotools buys you some useful commands like:
* @code
* make uninstall
* @endcode
*
* This uninstalls the software after it is installed with "make install".
* It is very useful to clear up what you built if you wish to clean the
* system.
*
* @code
* make distcheck
* @endcode
*
* 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.
*
* @code
* make clean
* @endcode
*
* This cleans up all build files (binaries, objects etc.) from the tree.
*
* @code
* make distclean
* @endcode
*
* This cleans out all the files from the build and from configure's output too.
*
* @code
* make maintainer-clean
* @endcode
*
* This deletes all the files autogen.sh produces so the tree is clean
* to be put into a revision-control system (like CVS, SVN, or GIT for example).
*
* There is a more advanced way of making use of the quicklaunch infrastructure
* in Elementary (which is not covered here due to its more advanced
* nature).
*
* Now let's actually create an interactive "Hello World" GUI on which you can
* click the OK button to exit. It's more code because this now does something
* much more significant, but it's still very simple:
*
* @code
* #include <Elementary.h>
*
* static void
* on_done(void *data, Evas_Object *obj, void *event_info)
* {
* // Quit the mainloop (elm_run function will return)
* elm_exit();
* }
*
* EAPI_MAIN int
* elm_main(int argc, char **argv)
* {
* Evas_Object *win, *box, *lab, *btn;
*
* // New window - do the usual and give it a name (hello) and title (Hello)
* win = elm_win_util_standard_add("hello", "Hello");
* // When the user clicks "close" on a window there is a request to delete
* evas_object_smart_callback_add(win, "delete,request", on_done, NULL);
*
* // Add a box object - default is vertical. a box holds children in a row,
* // Either horizontally or vertically. nothing more.
* box = elm_box_add(win);
* // Make the box horizontal
* elm_box_horizontal_set(box, EINA_TRUE);
* // Add object as a resize object for the window (controls window minimum
* // Size as well as gets resized if window is resized)
* elm_win_resize_object_add(win, box);
* evas_object_show(box);
*
* // Add a label widget, set the text and put it in the pad frame
* lab = elm_label_add(win);
* // Set default text of the label
* elm_object_text_set(lab, "Hello out there world!");
* // Pack the label at the end of the box
* elm_box_pack_end(box, lab);
* evas_object_show(lab);
*
* // Add an ok button
* btn = elm_button_add(win);
* // Set default text of button to "OK"
* elm_object_text_set(btn, "OK");
* // Pack the button at the end of the box
* elm_box_pack_end(box, btn);
* evas_object_show(btn);
* // Call on_done when button is clicked
* evas_object_smart_callback_add(btn, "clicked", on_done, NULL);
*
* // Now we are done, show the window
* evas_object_show(win);
*
* // Run the mainloop and process events and callbacks
* elm_run();
* elm_shutdown();
* return 0;
* }
* ELM_MAIN()
* @endcode
*
