SUMMARY="C-style arbitrary precision calculator"
DESCRIPTION="Calc is an interactive calculator which provides for easy large \
numeric calculations, 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."
