msfupdate switches

[Eric <dkn4a1 () gmail com>]

can anyone brief about the switches with *msfupdate*?

as, while updating, noticed that first column shows letters like A, D, U,
etc.
As far as I guessed, stands for A-Auxiliary, D-Download, U-Upload...

Am I right?
if so, why is it uploading things from *my system*?

also, there was something suspicious row...
U    HACKING

which, i never noticed before.
Would someone like to explain, or am I being just paranoid?
