This last email was some time ago and the situation evolved a bit.
* The list of packages to do in order to have the main packages of
Bioconductor is (I expect, I have not checked yet) around 60 to 70.
I can maintain some but I don't want to do all myself, especially since
my situation might change quite a bit in January.
Creating the specfile is not hard, here is a small python script that
helps to generate the specfile 
Maintaining those packages is not really difficult, there is 1 release
every 6 month (for each major release of R).
I developed a small python script  that handle most of the work, I
still have some ideas to improve it (I want to really personalize it for
I have been looking a bit at the dependencies question.
There is 20 main libraries of Bioconductor (based on what the biocLite
script install by default). The list is presented here
With the help of Torbjorn on #R (irc.freenode.net
) I modified a small
perl script that goes on the bioconductor SVN and for each packages
retrieve both the depends and suggests dependencies.
The results is available here:
To compare with
When there is only the Depends taken into account.
From that list I used this script to process the dependencies and
sub-dependencies that we would need to package.
The results are presented here:
The number of libraries to package jump from 36 to 75 if we take into
account the Suggests dependencies.
This only takes into account the dependencies of the software part of
Bioconductor, the libraries called 'metadata' or 'experiment data' which
I believe can also have sub-dependencies are not presented here.
This can give us some insight on where to start.
However I would like to know what you, guys, think of the question
dependencies "Depends" vs "Depends+Suggests".
"Suggests" add more work and leads to the problem of circular references
I have not heard from you about the global idea, do you
like/appreciate/don't care about it ? (cross out the wrong option)
