"""Determine the version number of the current tree.
|
|
|
|
This should be run after 'setup.py darcsver'. It will emit a single line of text
|
|
to stdout, either of the form '0.2.0' if this is a release tree (i.e. no patches
|
|
have been added since the last release tag), or '0.2.0-34' (if 34 patches have
|
|
been added since the last release tag). If the tree does not have a well-formed
|
|
version number, this will emit 'unknown'.
|
|
|
|
The version string thus calculated should exactly match the version string
|
|
determined by setup.py (when it creates eggs and source tarballs) and also
|
|
the version available in the code image when you do:
|
|
|
|
from allmydata import __version__
|
