Comment 3 for bug 260519

bzr join --reference looks very promising! However, the documentation references old(?) formats unknown to me. I tried with 1.6.1-rich-root. Scenario:

a) existing branch with projectA
b) branch projectB within the A tree
c) bzr join --reference projectB
d) bzr status from projectA root

expected: projectB files should be "unchanged"
reality: projectB files are "unknown" - as well as projectB/.bzr

e) edit projectB/README (pre-existing)
f) bzr commit from projectA root

expected: include the README file in the changeset
reality: as projectB stays unknown, it is not included

Is there any doc available except the "help" text?
