- <p>If <c>run_test</c> is called without parameters, it prints all valid
- start flags to stdout.</p>
+ <p>With the optional flag:</p>
+ <pre>-erl_args</pre>
+ <p>it's possible to divide the options on the <c>run_test</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>run_test</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>If <c>run_test</c> is called with option:</p>
+ <pre>-help</pre>
+ <p>it prints all valid start flags to stdout.</p>
