The package defines one command, \stretchwith, which will insert its first argument between each pair of letters (or whatever) in its second argument. It is thus usable as a method for letterspacing (with a finite skip as first argument), or for filling a box's width (with an infinite stretch as first argument).

The package is part of the ncctools bundle.
