The author explains that he built the tool because of difficulties getting msp430-gcc to run and doesn't feel like screwing with mspgcc4.

I do recommend screwing with mspgcc4. It comes with a download-and-build script. It built flawlessly on my Linux box and compiled OpenChronos [1](the free firmware for the geek wristwatch) without problems so far.

Personally I was looking for a simple assembler, not a full blown C compiler to use on my OS X machine.

This seems to me a better fit for someone who want to assemble some small (or big) project. Seems a nice weekend project to test it out.

To be frank, the download-and-build script felt pretty horrible.
