Portacle

Portacle is a complet eIDE for Common LISP that you can take with you on a USB stick. It is multi platform and can be run on Windows (7+), MacOSX (10.11+) and Linux (3.13+). Since it does not require any complicated installation process, it is set up and running in no time. It lends itself very well both to absolute beginners of Lisp that just need a good starting point, as well as advanced users that want to minimise the time spent getting everything ready.
