Berkeley Logo (<A HREF="usermanual">download manual as text</A>)
(<A HREF="downloads/ucblogo.pdf">download manual as PDF</A>)
(<A HREF="announce">download readme</A>)
is a freeware interpreter that I wrote along with
several students. (Major contributors are Daniel van Blerkom, Khang Dao,
Michael Katz, Douglas Orleans, and Sanford Owings.)

Josh Cogliati and bunches of other volunteers:
dmalec, Barak A. Pearlmutter, janekr, hosiet, reinerh, atehwa, kilobyte, pahihu
