the $gBug is cleared. This is identical to the behaviour of
<code>reopen</code>.
+ <p>This command will only cause a bug to be marked as not done if no
+ version is specified, or if the <var>version</var> being marked found
+ is equal to the <var>version</var> which was last marked fixed. (If
+ you are certain that you want the bug marked as not done,
+ use <code>reopen</code> in conjunction with <code>found</code>.</p>
+
<p>This command was introduced in preference to <code>reopen</code>
because it was difficult to add a <var>version</var> to that command's
syntax without suffering ambiguity.
