I've renamed the rmgr as lsf rather than lsf-mpiwr as the -mpiwr only serves to add confusion.  If and when better LSF support comes along it can share the same rmgr setting.  I also changed lsf_mpi to lsf_mode and gave it string values instead of int values as well as this should make the code easier to read.

Thank you very much for the patch, I'm back from Holiday now so have some time to look at this again.

I've committed a variant as r388.  I hope I haven't broken anything but can you test it please.  I'm interested to see the output if a valid LSF job is specified but it doesn't use a wrapper of the correct style, is a correct and clear error message given in this case?  As I said I don't have access to LSF myself so I've tried to keep any changes to a minimum.

Ashley,
