What good are the logs?

[Dylan Paul Thurston]

Sorry to ask a stupid question, but what good are the logs that GnuCash
writes out?  They have lots of information, but I can't see any convenient
way to use it (without doing some programming).

In particular, when I forget to quit GnuCash before quitting X, I seem
to get a log file but no saved account file.  How can I recover my
edits?

Thanks,
