Splat is the Smudge Platform: Libraries and Toolchain, a combined distribution of the Smudge compiler and the Smear library.
It is one-stop shopping for your Smudge needs, meant to be a batteries-included package for development of applications.
There are binary releases available for Windows and Linux available on the Splat releases page.
