Another tool is ufed (use flag editor).  Nicely combines flag name, set 
state, and
brief description.

 From this thread, I realized I hadn't ever reviewed my use flags, just 
added ones
as needed for the past 1.5 years.  So added the -* to start with.  A few 
surprises
like tetek.  Found a half dozen deprecated flags.  Then using ufed I 
discovered
several new flags to try.

This has me wondering if there is a utility to help manage the use 
flags.  I'd like
to know:

* Which use flags I have set that are not used by anything I have installed.
* Which use flags are deprecated.
* Which use flags are new.

Ideally I'd just add this to my daily.cron job.

Thank you,
Roy
