I'm trying to define a dependency on a group of BaselineOf.

specifically #core of github://pharo-graphics/Bloc/src.

I've looked at this https://github.com/Metacello/metacello/blob/master/docs/GettingStartedWithGitHub.md#create-baseline

which recommends using import:provides:

baseline: spec
  <baseline>

  spec for: #common do: [
    "Sample defines the group 'default'"
    spec baseline: 'Sample' with: [
      spec repository: 'github://dalehenrich/Sample:master' ].
    spec import: 'Sample' provides: #('default').

    "OtherSample *also* defines the group 'default'"
    spec baseline: 'OtherSample' with: [
      spec repository: 'github://dalehenrich/Sample:master' ].
    spec import: 'OtherSample' provides: #('default').

    "'default' can now be successfully resolved, even though
    both projects define the same name"
    spec package: 'OtherProject-Core with: [
      spec requires: 'default' ] ].

However this code is confusing... both Sample & OtherSample provide `default`, so on what does `OtherProject-Core` actually depend?

In the examples here https://github.com/Metacello/metacello/blob/master/docs/LockCommandReference.md there are groups with the name of the project in them ('External Core' 'External Tests'), but this won't work if I don't control the project I am loading, plus it feels like a hackish workaround.

Also, can it be unified with the way ConfigurationOf works?

Thanks,

Peter
