mary is an optimizing native code Forth compiler for Microchip PIC microcontrollers. It's an Open Source project published under the GNU license, so I conserve all the rights to the code but grant an explicit permission for everybody to take the sources and modify or redistribute it in the same conditions.

Latest version is 1.0a51, so it's in alpha stage and not finished. However, it's very close to beta and documentation is not too bad :) There may be important changes before reaching beta.

mary requires an ANS Forth system whose cell width is at least 16 bits. gforth 0.4.0 on a Linux/Intel platform for developing and testing, so comments about different systems are welcome.
