String const logStartMarker

These are used when serializing log messages over stdout.

Serialized logs must be preceded with the logStartMarker on its own line, and terminated with a logEndMarker also on its own line.

This allows multi-line logs to be sanely serialized via stdout, and mixed with other generic messages.


const logStartMarker = 'BUILD DAEMON LOG START';
