This package builds squint, the Newsqueak interpreter, on Linux. It should be easy to get to work on other Unix variants. It has no graphics support, although vestiges exist in the source. The package also includes a small subset of the Plan 9 C library because it was easier to include it than to remove squint's dependency on the installable print format stuff.

BUILDING

Run `make all' in this directory. Everything should compile without warnings.

TESTING

After building, cd squint and try squint progs/sieve2 You should see some prime numbers.

Additionally, 'make regress' in the squint directory will run some tests and check the output.

DOCUMENTATION

The man directory contains information about the print library. The doc directory contains a reference manual and a paper about implementation, taken from

The Implementation of Newsqueak
    Rob Pike
    Software - Practice and Experience, Jul 1990
    Vol 20 #7, pp 649-659

That same issue has a paper by Doug McIlroy that is necessary reading, but I don't have a .ps version of the paper.
