# Clean up the history file. 10 Record types: MAR OFT WUCG
|

|

# WUCG records are thrown out.
|

# MAR records are retained.
|
|
# T records: retain only last tag with same combined tag/module.

|
|
# Two passes: Walk through the first time and remember the
|
|
# 1. Last Tag record with same "tag" and "module" names.
|
|
# 2. Last O record with unique user/module/directory, unless followed
|
|
# by a matching F record.
