herkforth
herkforth is currently a development environment for GNU/Linux. This is being used to create the Fronds Operating System, but beyond that probably won't be used except for learning purposes.
The herkforth mission was to make computer use dramatically more productive and peaceful. Hopefully this dream will be achieved through fronds.
CURRENT STATUS: Compiler, assembler, code editor and interpreter working very nicely under GNU/Linux. herkforth ran directly under Open Firmware but this feature has not been tested for years.
herkforth is free software, available under the terms of the GNU GPL.
