I have been considering if it would be a good idea to (conditionally?)
compress certain collection files.  In some cases they are actually
rather large and I suspect compression will generally be good in such
cases[1].  Admittedly, there are also cases where it gives little to
no size reduction.

Code-wise, we should be able to able this for file-info without any
greater hassle than updating L::Collect::Package and coll/file-info.
There are still some "ad-hoc" index parsers left in coll/*, but it
should be fairly straight forward to fix.

However, there has been people doing things like "grep -r $expression"
on the lab in the past[2] and compression could break some of these.

For reference, the size of the lab pool is 16 (13) GB according to
 du -sh (--apparent-size)

Today, our Laboratory size has dropped to 10 (6.1) GB according to du
-csh (--apparent-size).  And this is despite the fact that we now also
process experimental (~10% extra packages).  Yummy!
