Import algol68g-2.2.0 as wip/algol68g.

The development of Algol played an important role in establishing
computer science as an academic discipline. The Algol 68 Genie project
preserves Algol 68 out of educational as well as scientific-historical
interest, by making available Algol 68 Genie; a recent, well-featured
implementation written from scratch. Algol 68 Genie is a practically
full implementation of the language defined by the Revised Report. The
implementation is a hybrid compiler-interpreter; units with considerable
interpreter-overhead can optionally be compiled.
