-\section intro_sec Introduction
-The goal of this GSoC project is to automate the testing of testsprite2.
-testsprite2 takes 26 parameters which have thousands of valid combinations and is
-used to validate SDL's window, mouse and rendering behaviour. By having a test
-harness that runs testsprite2 with various command line argument strings and
-validates the output for each run, we can make testing an easier task for
-maintainers, contributors and testers. The test harness can be used by a continuous
-integration system (like buildbot or jenkins) to validate SDL after checkins.
-
-SDL Homepage: http://libsdl.org/
-
-\section build_sec Building
-
-\subsection build_linux Building on Linux/Cygwin
-<tt>./autogen.sh; ./configure; make;</tt>
-
-\subsection build_windows Building on Windows
-Use the Visual Studio solution under \c SDL/VisualC/visualtest.
-
-\section docs_sec Documentation
-Documentation is available via Doxygen. To build the documentation, cd to the
-SDL/visualtest/docs directory and run \c doxygen. A good starting point for
-exploring the documentation is \c SDL/visualtest/docs/html/index.html
-
-\section usage_sec Usage
-To see all the options supported by the test harness, just run \c testharness
-with no arguments.
-
-At the moment the following options are supported:
-\li \c sutapp - Path to the system under test (SUT) application
-\li \c sutargs - Launch the SUT with the specified arguments string
-\li \c timeout - The maximum time after which the SUT process will be killed;
-	passed as hh:mm:ss; default 00:01:00
-\li \c variator - Which variator to use; see \ref variators_sec
-\li \c num-variations - The number of variations to run for; taken to be 
-	1 for the random variator and ALL for the exhaustive variator by default
-\li \c no-launch - Just print the arguments string for each variation without
-	launching the SUT or performing any actions
-\li \c parameter-config - A config file that describes the command line parameters
-	supported by the SUT; see \ref paramconfig_sec or the sample *.parameters files
-	for more details
-\li \c action-config - A config file with a list of actions to be performed while
-	the SUT is running; see \ref actionconfig_sec or the sample *.actions files
-\li \c output-dir - Path to the directory where screenshots should be saved; is
-	created if it doesn't exist; taken to be "./output" by default
-\li \c verify-dir - Path to the directory with the verification images; taken to 
-	be "./verify" by default
-
-Paths can be relative or absolute.
-
-Alternatively, the options can be passed as a config file for convenience:
-
-<tt>testharness \-\-config testsprite2_sample.config</tt>
-
-For a sample, take a look at the *.config files in this repository.
-
-We can also pass a config file and override certain options as necessary:
-<tt>testharness \-\-config testsprite2_sample.config \-\-num-variations 10</tt>
-
-Note: You may find it convenient to copy the SUT executable along with any
-resources to the test harness directory. Also note that testsprite2 and its
-resources (icon.bmp) are automatically copied when using the Visual Studio
-solution.
-
-\subsection usageexamples_subsec Usage examples:
-
-Passing a custom arguments string:
-<tt>testharness \-\-sutapp testsprite2 \-\-sutargs "\-\-cyclecolor \-\-blend mod
-\-\-iterations 2" \-\-action-config xyz.actions</tt>
-
-Using the random variator:
-<tt>testharness \-\-sutapp testsprite2 \-\-variator random \-\-num-variations 5
-\-\-parameter-config xyz.parameters \-\-action-config xyz.actions</tt>
-
-\subsection config_subsec Config Files
-Config files are an alternate way to pass parameters to the test harness. We
-describe the paramters in a config file and pass that to the test harness using
-the \-\-config option. The config file consists of lines of the form "x=y" where
-x is an option and y is it's value. For boolean options, we simply give the name
-of the option to indicate that it is to be passed to the testharness.
-
-The hash '#' character can be used to start a comment from that point to the end
-of the line.
-
-\section paramconfig_sec The SUT Parameters File
-To generate variations we need to describe the parameters the will be passed to
-the SUT. This description is given in a parameters file. Each line of the parameters
-file (except the blank lines) represents one command line option with five
-comma separated fields:
-<tt>name, type, values, required, categories</tt>
-
-\li \c name is the name of the option, e.g., \c \-\-cyclecolor.
-\li \c type can have one of three values - integer, boolean and enum.
-\li \c values - for integer options this is the valid range of values the option
-	can take, i.e., [min max]. For enum options this is a list of strings that
-	the option can take, e.g., [val1 val2 val3]. For boolean options this field
-	is ignored.
-\li \c required - true if the option is required, false otherwise.
-\li \c categories - a list of categories that the option belongs to. For example,
-	[video mouse audio]
-
-Just like with config files, hash characters can be used to start comments.
-
-\subsection additionalnotes_subsec Additional Notes
-
-\li If you want to have an option that always takes a certain value, use an enum
-	with only one value.
-\li Currently there isn't any way to turn an option off, i.e., all options will
-	be included in the command line options string that is generated using the
-	config. If you don't want an option to be passed to the SUT, remove it from
-	the config file or comment it out.
-
-\section variators_sec Variators
-Variators are the mechanism by which we generate strings of command line arguments
-to test the SUT with. A variator is quite simply an iterator that iterates through
-different variations of command line options. There are two variators supported at
-the moment:
-\li \b Exhaustive - Generate all possible combinations of command line arguments
-	that are valid.
-\li \b Random - Generate a random variation each time the variator is called.
-
-As an example, let's try a simple .parameters file:\n
-<tt>
-\-\-blend, enum, [add mod], false, [] \n
-\-\-fullscreen, boolean, [], false, []
-</tt>
-
-The exhaustive variator would generate the following four variations:\n
-<tt>
-\-\-blend add \n
-\-\-blend mod \n
-\-\-blend add \-\-fullscreen \n
-\-\-blend mod \-\-fullscreen \n
-</tt>
-
-The random variator would simply generate a random variation like the following:\n
-<tt>\-\-blend mod</tt>
-
-\section actionconfig_sec The Actions File
-Once the SUT process has been launched, automated testing happens using a mechanism
-called actions. A list of actions is read from a file and each action is performed
-on the SUT process sequentially. Each line in the actions file describes an action.
-The format for an action is <tt>hh:mm:ss ACTION_NAME additional parameters</tt>.
-There are five actions supported at the moment:
-\li \b SCREENSHOT - Takes a screenshot of each window owned by the SUT process. The
-	images are saved as \c [hash]_[i].bmp where \c [hash] is the 32 character long
-	hexadecimal MD5 hash of the arguments string that was passed to the SUT while
-	launching it and \c i is the window number. i = 1 is an exceptional case
-	where the \c _[i] is dropped and the filename is simply \c [hash].bmp\n
-	Note: The screenshots are only of the window's client area.
-\li \b VERIFY - Verifies the screenshots taken by the last SCREENSHOT action by
-	comparing them against a verification image. Each \c [hash]_i.bmp image output
-	by the SCREENSHOT action is compared against a \c [hash].bmp image in the
-	verify-dir.
-\li \b QUIT - Gracefully quits the SUT process. On Windows this means sending a
-	WM_CLOSE message to each window owned by the SUT process. On Linux it means
-	sending a SIGQUIT signal to the SUT process.
-\li \b KILL - Forcefully kills the SUT process. This is useful when the SUT process
-	doesn't respond to the QUIT action.
-\li <b>LAUNCH [/path/to/executable] [args]</b> - Runs an executable with \c [args]
-	as the arguments string.
-
-Just like with config files, hash characters can be used to start comments.
-
-\section contint_sec Continuous Integration (CI)
-One of the goals of the project was to create a test harness that integrates
-with CI systems to provide automated visual and interactive testing to SDL.
-
-At the moment the test harness can be run in two modes that are useful for CI:
-\li Crash testing mode - launch the SUT with every variation and all parameters,
-	report to the CI if there's a crash
-\li Visual testing mode - launch and visually verify the SUT for a smaller subset
-	of the parameters
-
-Look at the launch_harness.sh/launch_harness.cmd for an example scripts that run the
-test harness for all variations with all parameters and report an error on a crash.
-The script uses the testsprite2_crashtest config, so remember to copy those files
-over to the test harness executable directory along with the script.
-
-\section todo_sec TODOs
-\li Allow specifying a clipping box along with the VERIFY action, i.e., hh:mm:ss
-	VERIFY x, y, w, h
-\li Add support for spaces between the equals sign in test harness config files
-\li Implement the SCREENSHOT action on Linux
-\li Add a pairwise variator
-\li Add actions to inject keyboard/mouse events
-\li Add actions to manipulate the SUT window, e.g., minimize, restore, resize
-\li Add support to load and save screenshots as .pngs instead of .bmps
-
-\section issues_sec Known Issues
-\li The QUIT action does not work on a testsprite2 process with multiple windows.
-	This appears to be an issue with testsprite2.
-\li The SCREENSHOT action doesn't capture the testsprite2 window correctly if the
-	--fullscreen option is supplied. It works with --fullscreen-desktop, however.

-\`configure' configures this package to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
