Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Reorganize to have a more conventional module structure. This means that hgsubversion now uses absolute imports instead of relative ones, which makes the tests more reliable.

1 '''integration with Subversion repositories
2
3 hgsubversion is an extension for Mercurial that allows it to act as a Subversion
4 client, offering fast, incremental and bidirectional synchronisation.
5
6 Please note that hgsubversion should not be considered stable software. It is
7 not feature complete, and neither guarantees of functionality nor future
8 compatability can be offered. It is, however, quite useful for the cases where
9 it works, and a good platform for further improvements.
10
11 Before using hgsubversion, we *strongly* encourage running the
12 automated tests. See `README' in the hgsubversion directory for
13 details.

15 The operation of hgsubversion can be customised with the following variables:
