What does dress frets mean?

Ages ago I had my guitar set up by a tech. On the receipt it said 'dressed frets', and I have wondered ever since what this means.

The list also included, feed fretboard, clean guitar and the usual stuff.

But whats dressing a fret? put it in a nice evening gown?
Over time steel strings wear down frets. Makes kind of little grooves in them. Dressing frets means sort of filing down and leveling the frets a little. And then I think they're polished too. Hope that helps.

Cleaning up sharp edges on them, and possibly leveling them to eliminate fret buzz at low action.
