How do you manage the label database?

[Yamuna Ramasubramaniyan]

Hello,

Our main development branch is open to all to submit
code.  The latest built source is identified by a
label that is reapplied every week (the tag is
reused).  I have a seperate branch on which I do the
builds - I merge from the development branch on to
this one every week.  This helps in keeping a snapshot
of the latest build's source.  All the build tags are
on this branch.  I use incremental tags on the
development branch to reproduce the build on the
development branch.  All this labeling is causing the
cvs log output to grow by leaps and bounds.  Is there
anyway to control this growth?

How do people manage obsolete tags?  After what length
of time do you consider a tag obsolete?  

How do people handle removed files when using a
recurring label?  When I checkout source using the
recurring label, I get files that were deleted during
earlier builds.  Do you delete the tag and reapply it
every time? 

Thanks a lot,

-Cheers,
