Contributors : Tom Schum, Thomas Okken
An OLPC-optimized skin requires by-hand installation of skin files into a .sugar subdirectory at the moment; to be integrated into future bundles directly.
Note: existing "standard" or "realistic" calculator image (skin) appears inconveniently small on OLPC screen, but all keys, functions, etc are working.
Two new skins optimized for OLPC are working.
Project home site is http://free42.sourceforge.net/

RPN in 25 words or less: "Give the calculator the numbers, then tell it what to do with them."
