I just tried

nfold.py --booster=Adaboost --folds=5 --data=spambase.data --
spec=spambase.spec --rounds=500 --tree=ADD_ALL --generate --dir=C:
\Users\Adam\Desktop\cvdata

in the dos-style command prompt. It didn'g vive a syntax error this
time, it just repeated my command back to me in text. I assume I
called code correctly, but it didn't make a new folder full of data
like it should have.
