I think both.
As your script, could be that i can define a package that do different
things (actions, checks, ...) for different install.
But also i can define different package for different OS.
Third, could be that i can define the same package (name) but with two
or more specification for two or more OS. But i think that this will
work good only in conjunction with some ''metapackage'' definition ala
The base rule are: leave to recipe writer the power: clearly if a
package is strictly os or arch tagged and cited on another package as
dependencies, wpkg will complain that package deps was not satisfiable.
But this does not brake WPKG logic nor add a real layer of complexity
in debugging recipe writing...

You're right, indeed there's no a big difference between yor script and
But i consider XML a more ''self documenting'' format, and really i
hate CMD scripting that turn in really unreadable pieces of code.
Apart that in XML there's a finer error handling, put every command in
a <install /> statement...
Clerarly, it's my opinion. ;-)
