[htdig] -a option for htpurge question

[Ted Stresen-Reuter]

Does passing the -a switch to htpurge cause it to work on .work 
databases if they already exist or does it overwrite existing .work dbs 
with it's own? The documentation does not make it clear:

http://www.htdig.org/dev/htdig-3.2/htpurge.html
I'm asking because the customized rundig.sh script I'm using runs 
htpurge -a after htdig -a but before moving the .work files to the live 
databases. In other words with an existing set of databases, I do 
(generally):

htdig -a
htpurge -a
copy .work to live dbs
when perhaps I should be doing:
htdig -a
copy .work to live dbs
htpurge -a
copy .work to live dbs
The documentation made me wonder if htpurge isn't actually operating on 
the databases that were created on the last run rather than on the 
current run (since, in the first scenario, the current dbs still have 
.work on them).

Any help?
