[Bioc-devel] biocLite suggestion

I recently had a look at the biocLite script as I was reinstalling  
stuff, and I have a few comments.

Currently it is difficult to see that the function actually accepts a  
groupName argument, and furthermore it is difficult to see what the  
possible values of that argument are (and what packages they  
corresponds to) - basically one has to source biocinstall manually  
and look for the code.

Suggestion:
1) explicitly add groupName to the args of the biocLite function
2) add in the comments section that groupName = "help" will print out  
the possible combinations of groupNames (and what packages they  
correspond to)
3) add code in the biocinstall.R script so that 2) actually is true.
(4)) possibly add the groupName = "help" comment to the output of the  
biocLite script (I am not sure whether this is a good idea, but it  
might be helpful for some non-power users?).

Otherwise the script is very nice.
