<p><b>Notes:</b> Beginning with NUnit 2.4, the /include and /exclude options may
   be combined on the command line. When both are used, all tests with the included
   categories are run except for those with the excluded categories.</p>

<p>Beginning with NUnit 2.4.6, you may use a <b>Category Expression</b> with either
of these options:
<dl>
	<dt>A|B|C
	<dd>Selects tests having any of the categories A, B or C.
	<dt>A,B,C
	<dd>Selects tests having any of the categories A, B or C.
	<dt>A+B+C
	<dd>Selects
