  <comsummary>Program used for starting Common Test from the
    OS command line.
  </comsummary>

  <description>
  <p>The <c>ct_run</c> program is automatically installed with Erlang/OTP
    and Common Test (please see the Installation chapter in the Common
    Test User's Guide for more information). The program accepts a number
    of different start flags. Some flags trigger <c>ct_run</c>
    to start the Common Test application and pass on data to it. Some
    flags start an Erlang node prepared for running Common Test in a
    particular mode.</p>

  <p>There is an interface function that corresponds to this program,
    called <seealso marker="ct#run_test-1"><c>ct:run_test/1</c></seealso>, for starting Common Test from the Erlang
    shell (or an Erlang program). Please see the <c>ct</c> man page for
    details.</p>

  <p><c>ct_run</c> also accepts Erlang emulator flags. These are used
    when <c>ct_run</c> calls <c>erl</c> to start the Erlang node
    (making it possible to e.g. add directories to the code server path,
    change the cookie on the node, start additional applications, etc).</p>

  <p>With the optional flag:</p>
  <pre>-erl_args</pre>
  <p>it's possible to divide the options on the <c>ct_run</c> command line into
    two groups, one that Common Test should process (those preceding <c>-erl_args</c>),
    and one it should completely ignore and pass on directly to the emulator
    (those following <c>-erl_args</c>). Options preceding <c>-erl_args</c> that Common Test
    doesn't recognize, also get passed on to the emulator untouched.
    By means of <c>-erl_args</c> the user may specify flags with the same name, but
    with different destinations, on the <c>ct_run</c> command line.</p>
  <p>If <c>-pa</c> or <c>-pz</c> flags are specified in the Common Test group of options
    (preceding <c>-erl_args</c>), relative directories will be converted to
    absolute and re-inserted into the code path by Common Test (to avoid
    problems loading user modules when Common Test changes working directory
    during test runs). Common Test will however ignore <c>-pa</c> and <c>-pz</c> flags
    following <c>-erl_args</c> on the command line. These directories are added
    to the code path normally (i.e. on specified form)</p>

  <p>Exit status is set before the program ends. Value <c>0</c> indicates a successful
    test result, <c>1</c> indicates one or more failed or auto-skipped test cases, and
    <c>2</c> indicates test execution failure.</p>

  <p>If <c>ct_run</c> is called with option:</p>
    <pre>-help</pre>
    <p>it prints all valid start flags to stdout.</p>
