[BioC] Problem with setQCEnvironment

Hi Melissa,

You got a warning, not an error (the difference being that R said 'Hmmm, 
that doesn't seem right.' rather than saying 'ERRRRRR crash boom thud!').

In other words, things should have worked anyway. Did they not?

Anyway, the problem here is that you didn't add a final carriage return 
when you created the .qcdef file. From ?readLines

warn: logical.  Warn if a text file is missing a final EOL.

Where EOL is (apparently obviously) an End Of Line character, which you 
create by hitting the Enter key.

Best,

Jim
