Automagically

/aw-toh-maj'i-klee/ or /aw-toh-maj'i-k*l-ee/

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."
