[BioC] getting a list of packages by biocView tags

[Roels, Steven]

Seth et al,

Is there an example somewhere of how to get a list of packages based on
one or more biocView tags (programmatically in R)?

For example:

Given a tag like "hgu133a2", get a matrix like that at:

http://www.bioconductor.org/packages/1.8/hgu133a2.html

which can then be used to build a list of desired
annotation/experiment/etc packages for subsequent install.

I was poking around in the new BiocViews package (which I assume is the
place to start), but the solution didn't leap out at me.

Having the biocView tags is great and I'd love to take full advantage of
them.

Maybe biocView tags and/or patterns could ultimately be supplied as
arguments to getBioC(). 

Thanks,

-Steve
