Declare Tag
The declare tag is used to declare identifiers for remote interpreter

the remote interpreter is specified to the current interpreter using the
declare tag.
Declaration is done in the tag body as.
vsr identifier
ex:-
<declare>
vsr server,
vsr mail,
</declare>
Later messages can be sent to the remote interpreters as
mail.print(hello there),
