+# BattOr

[charliea (OOO until 10-5), 2017/03/20 14:37:38]

nit: given that this is for a unit test, just keep like ten lines of the trace.
no reason to store more than is necessary to make a point that this is a battor
test data file.

if you do store 500 lines, you run the risk of someone thinking there's a reason
why you need to.

Done.
