Control directories will also have the notion of an "active" branch. This is
68
the branch that is being used by a working tree, if present and the branch

that will be used if no explicit colocated branch is specified. The

active branch support makes it easier to deal with existing bzrdirs and

is useful when accessing foreign control directories that have the concept

Eventually, Bazaar could easily support colocated branches by just
118
118
creating a new branch transport for each colocated branch and have a
119
119
"regular" branch live there. This would require something like
120
BzrDirMeta2 though. An example of this is implemented in the
