+Calc is an interactive calculator which provides for easy large
+numeric caluclations, but which also can be easily programmed for
+difficult or long calculations. It can accept a command line
+argument, in which case it executes that single command and exits.
+Otherwise it enters interactive mode. In this mode, it accepts
+commands one at a time, processes them, and displays the answers.
+In the simplest case, commands are simply expressions which are
+evaluated. For example, he following line can be input:
+> 3 * (4 + 1)
+and the calculator will print 15.
+
+Commands are statements in a C-like language, where each input line
+is treated as the body of a procedure. Thus he copmmand line can
+contain variable declarations, expressions, labels, conditional
+tests, and loops. Assignments to any variable name will automatically
+define that name as a global variable.
+
+For more information on the program, run 'calc help help'.
