Programmatically finding dependencies for a Portfile

[Artur Szostak]

Thanks,

    set mport [mportopen "file:///tmp/testport" [list subport "testsubport"] [list]]

Is exactly what is needed to select data for a specific subport.

Cheers

Artur

If you want a specific subport, you would need to give its name in the
list of options here. This list of options consists of pairs of key and
value as list items.

set mport [mportopen "file:///tmp/testport" [list subport "testsubport"] [list]]

Unfortunately, the internal API is very sparsely documented if at all...

There is a section dedicated to it in the the guide, but as you already
got this far, you seem to know most of its content already.

Hope that helps,
