-Log File Format
----------------
-
-.. py:class:: buildbot.status.logfile.LogFile
-
-The master currently stores each logfile in a single file, which may have a
-standard compression applied.
-
-The format is a special case of the netstrings protocol - see
-http://cr.yp.to/proto/netstrings.txt.  The text in each netstring
-consists of a one-digit channel identifier followed by the data from that
-channel.
-
-The formatting is implemented in the LogFile class in
-:file:`buildbot/status/logfile.py`, and in particular by the :meth:`merge`
-method.
