Frowns is a chemoinformatics toolkit geared toward rapid development of chemistry related algorithms. It is written in almost 100% Python with a small portion written in C++.
Frowns is loosely based on the PyDaylight API that Andrew Dalke wrote to wrap the daylight C API. In some cases programs written using PyDaylight will also work under Frowns with a few minor changes. A good overview of PyDaylight is available at here.
A good place to look at what Smarts and Smiles are is at the daylight web site located at http://www.daylight.com/
