The canonical starting place for rpython is this page [0] in the rpython 
documentation. It is a bit old, so please raise an issue if something 
does not work right. There are some examples in 
rpython/translator/goal/, the targetnopstandalone.py one is close to 
what you are trying to do. If you call


python2 rpython/bin/rpython -O2 
rpython/translator/goal/targetnopstandalone.py


you will get an executable in 
$tmp/usession*/testing_1/targetnopstandalone-c that will print "hello world"
