velocity user guide - addition

[Jean Francois Chamard <jf...@interstructure.ca>]

Hi there,
    I played with something thismorning and perhaps it would be nice to 
have in the "Velocimacro Miscellany" section in the user guide.

I saw somewhere (in the velocity wiki perhaps?) that you could call a 
macro and put it in a var
Example: #set($myvar="#mymacro($param)")

Today, I needed to do something like
#set($myvar="#mymacro("String")")
which throw a parsing error.... so you could do
#set($myvar="String")
#set($myvar2="#mymacro($myvar)")

But this is also working, it just looks nicer
#set($myvar="#mymacro('String')")

The next example could not work because the singlequote doesn't parse 
(so you would need to use 2 #set ..)
#set($myvar="#mymacro('String$aVarToConcatenate')")

I hope it was useful
Jeff
