"""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.

usage:

    testbzr [-p PYTHON] [BZR]

By default this tests the copy of bzr found in the same directory as

testbzr, or the first one found on the $PATH.  A copy of bzr may be

given on the command line to override this, for example when applying

a new test suite to an old copy of bzr or vice versa.

testbzr normally invokes bzr using the same version of python as it

would normally use to run -- that is, the system default python,

unless that is older than 2.3.  The -p option allows specification of

a different Python interpreter, such as when testing that bzr still

works on python2.3.

This replaces the previous test.sh which was not very portable."""
