-## fwbuilder/configlets/sveasoft/ in your home directory and modify it.
-## Double "##" comments are removed during processing but single "#"
-## comments are be retained and appear in the generated script. Empty
-## lines are removed as well.

-## Configlets support simple macro language with these constructs:
-## {{$var}} is variable expansion
-## {{if var}} is conditional operator.
