Export source from herkforth

herkforth can export the source back to ascii files. Here's how:

1) Make a directory named out in the current directory.

2) Type "export" (without quotes) and press RETURN.

3) This will save all the blocks to normal text files in the out folder. These files are 100% compatible with the herkforth bootstrapping process. See: herkforth source code management.
