This tool's purpose is to help you determine which revision of a subversion
repository contains a change. It does this by employing a binary search. It
will manage the current revision of your checkout directory, and narrow in on
the target revision, as you give it clues about the current revision such as
"before" (this revision is before the one you want) or "after" (this revision
is after the one you want).

Start a bisect session with the "start" command. Then, walk the binary tree by
using the "before" and "after" commands. When you are done, the tool will tell
you the target revision.

The most common usage scenario is finding out which rev a bug was introduced
in. For this purpose, some command aliases have been added: if the current
revision contains the bug, you can use the "bad" command (meaning, this
revision is "after" the change you want to find), otherwise use the "good"
command (meaning, this revision is "before" the change you want to find).

All commands should be run from within a subversion checkout directory. After a
"svn-bisect start", all subsequent svn-bisect commands need to be run from that
same directory.
