automagically

automagically /aw-toh-maj'i-klee/ adv.  Automatically, but
   in a way that, for some reason (typically because it is too
   complicated, or too ugly, or perhaps even too trivial), the speaker
   doesn't feel like explaining to you.  See {magic}.  "The
   C-INTERCAL compiler generates C, then automagically invokes
   `cc(1)' to produce an executable."
