I'm familiar with it. However, it works best for something where
there is little reason to change your mind on the fly, like your
mail server or /bin/sh shell. Mawk and gawk aren't all that
different: you typically want gawk, unless you are resource-constrained,
and then you go with mawk.

Big as a house, much bigger than a house, it looked to [Sam], a grey-clad
moving hill. Fear and wonder, maybe, enlarged him in the hobbit's eyes,
but the Mumak of Harad was indeed a beast of vast bulk, and the like of him
does not walk now in Middle-earth; his kin that live still in latter days are
but memories of his girth and his majesty. --"Of Herbs and Stewed Rabbit"
