Using Delphi Subversion integration to check files in from another folder

So we're converting from VSS to delphi and we use a lot of include paths.

We'd like to at least attempt to conform to whatever the Delphi IDE decides is the right way to do this, but it's non-obvious.

Apparently, you can't include files in SVN that are used in a different folder, even if they are mentioned in the project group.

So... what is the expectation? Do we have to convert all our files to use namespaces and put them开发者_高级运维 in the same folder just to use Delphi's subversion integration completely?

Should we create BPL's for all of our 'unprojected' common files that are shared between multiple DLLs?
