<br>
Link towards another block: up to 4 arguments. <ul>
 <li>Argument 1: the name of the cited block. This can be a block of another
document, in this case this argument must be under the form <tt>ser/bl</tt>,
where <tt>ser</tt> is the serial number of the other document, and <tt>bl</tt>
the name of the block.<br>
 If this argument is empty or equal to '.', it means the current block.
 <li>Argument 2 (optional): the title of the link. (This defaults to the title
 of the cited block.)
 <li>Argument 3 (optional): the position to go (anchor) in the cited block.
 <li>Argument 4 (optional): parameter string. Parameters should be of the form <tt>parm1=...&parm2=...&parm3=...</tt> Up to 20 parameters can be used. These parameters can then be used in the linked-to document, under the names of <tt>\\parm1, \\parm2, ...</tt>.
</ul>
<p>
For example, to add a link to the entry block (<tt>main</tt>) of this
document, it is enough to type <tt>\\link{main}</tt>, and the result is
\link{main}.
<p>
<a name=parmlink>
Example of passing parameters: the command

<tt>\\link{.}{try this one}{parmlink}{parm1=10&parm2=20}</tt>

gives \link{.}{try this one}{parmlink}{parm1=10&parm2=20}</tt>. Now \\parm1=\parm1, \\parm2=\parm2.
