"""External black-box test for bzr.

This always runs bzr as an external process to try to catch bugs

related to argument processing, startup, etc.

testbzr [-p PYTHON] [BZR]
30
By default this tests the copy of bzr found in the same directory as
31
testbzr, or the first one found on the $PATH. A copy of bzr may be
32
given on the command line to override this, for example when applying
33
a new test suite to an old copy of bzr or vice versa.
35
testbzr normally invokes bzr using the same version of python as it
36
would normally use to run -- that is, the system default python,
37
unless that is older than 2.3. The -p option allows specification of
38
a different Python interpreter, such as when testing that bzr still
