Link towards another block: up to 4 arguments. 
 
- 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 ser/bl,
where ser is the serial number of the other document, and bl
the name of the block.
 If this argument is empty or equal to '.', it means the current block.
 
- Argument 2 (optional): the title of the link. (This defaults to the title
 of the cited block.)
 
- Argument 3 (optional): the position to go (anchor) in the cited block.
 
- Argument 4 (optional): parameter string. Parameters should be of the form parm1=...&parm2=...&parm3=... Up to 20 parameters can be used. These parameters can then be used in the linked-to document, under the names of \\parm1, \\parm2, ....

For example, to add a link to the entry block (main) of this
document, it is enough to type \\link{main}, and the result is
\link{main}.

Example of passing parameters: the command

\\link{.}{try this one}{parmlink}{parm1=10&parm2=20}

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