[BioC] Question about using Biostrings & BSgenome

[J.delasHeras at ed.ac.uk]

I haven't yet used either of these packages, but it looks like  
something I may want to look at.

I was wondering if I can use these packages together with something  
like 'BSgenome.Hsapiens.UCSC.hg18' to extract sequences around every  
TSS, for instance.
I have a couple of different oligo array designs, both in human and  
mouse, and I would like to subset probes according to a number of  
criteria, such as "promoter", "intergenic", etc...
I'm not yet familiar with these packages but I suspect they will  
provide all teh tools I need to extract and "play" with genomic  
sequences.

Am I right?

Anybody has some examples to help me get a better overview, beyond  
those in the vignettes?

Thanks.

Jose
