Cool is based on Sather164, which is itself based on the language Sather. Portions of this document were cribbed from the Sather164 manual; in turn, portions of the Sather164 manual are based on Sather documentation written by Stephen M. Omohundro.
A number people have contributed to the design and implementation of Cool, including Manuel Fähndrich, David Gay, Douglas Hauge, Megan Jacoby, Tendo Kayiira, Carleton Miyamoto, and Michael Stoddart. Joe Darcy updated Cool to the current version.
This version (used in Virginia Programming Language Design and Implementation courses) of Cool owes a great debt to George C. Necula and Bor-Yuh Evan Chang.
