Es

Es is an extensible Unix shell with first class functions, lexical scope, exceptions, and rich return values. Its language derives from the Plan 9 shell rc and was influenced by Scheme and Tcl. Extensibility comes from modifying builtin services such as path searching and redirection. The site gathers patches and information to keep es running on modern Unices.
