As all Velocity references ( "$xxx" ) are references of Java objects, sometimes it could be useful to know the object's class. To do this, just use "class.name" (full name with package) or "class.simpleName" (only the class name without package)
#set( $v = 12 )
#set( $s = "abc" )
Generate a file only once
Sometimes it can be useful to make sure you only generate a file once to avoid overwriting manual changes after project bootstrapping. Since Telosys 3.3.0 you can do that with #cancel directive.
##--- NB : do not rewrite the file if it already exists
