Synopsis:
    php run-tests.php [options] [files] [directories]

Options:
    -l <file>   Read the testfiles to be executed from <file>. After the test 
                has finished all failed tests are written to the same <file>. 
                If the list is empty and no further test is specified then
                all tests are executed (same as: -r <file> -w <file>).

    -r <file>   Read the testfiles to be executed from <file>.

    -w <file>   Write a list of all failed tests to <file>.

    -a <file>   Same as -w but append rather then truncating <file>.

    -c <file>   Look for php.ini in directory <file> or use <file> as ini.

    -n          Pass -n option to the php binary (Do not use a php.ini).

    -d foo=bar  Pass -d option to the php binary (Define INI entry foo
                with value 'bar').

    -m          Test for memory leaks with Valgrind.
    
    -N          Always set (Test with unicode_semantics set off in PHP 6).
    
    -s <file>   Write output to <file>.

    -q          Quiet, no user interaction (same as environment NO_INTERACTION).

    --verbose
    -v          Verbose mode.

    --help
    -h          This Help.

    --html <file> Generate HTML output.
	
    --temp-source <sdir>  --temp-target <tdir> [--temp-urlbase <url>]
                Write temporary files to <tdir> by replacing <sdir> from the 
                filenames to generate with <tdir>. If --html is being used and 
                <url> given then the generated links are relative and prefixed
                with the given url. In general you want to make <sdir> the path
                to your source files and <tdir> some pach in your web page 
                hierarchy with <url> pointing to <tdir>.

    --keep-[all|php|skip|clean]
                Do not delete 'all' files, 'php' test file, 'skip' or 'clean' 
                file.

    --show-[all|php|skip|clean]
                Show 'all' files, 'php' test file, 'skip' or 'clean' file.

    --no-clean  Do not execute clean section if any.
