# uSCXML ReadMe

uSCXML is a SCXML interpreter written in C/C++. It is still in a rather early stage but mostly
feature-complete as far as the W3C SCXML draft specifies. It runs on most <b>Linux</b>,
<b>Windows</b> and <b>MacOSX</b>, each 32- as well as 64Bits. 

There is no technical reason for it not to run on iOS and Android as well, but we did not yet setup
the respective build-process.
