%description
Calc is an arbitrary precision C-like arithmetic system that is a
calculator, an algorithm-prototyper, and a mathematical research tool. Calc
comes with a rich set of built-in mathematical and programmatic functions.


%package libs
Summary:       Libraries for the calc arithmetic system

%description libs
Shared libraries used by the calc command line calculator and other programs
using its arbitrary precision arithmetic routines.


%package devel
Summary:        Development files for the calc arithmetic system
Requires:       %{name}-libs = %{version}-%{release}

%description devel
This package contains files necessary to build applications which use the
calc arbitrary precision arithmetic system.


%package stdrc
Summary:      Standard resource files the calc arithmetic system
Requires:     %{name} = %{version}-%{release}

%description stdrc
This package contains the standard calc resource files and several calc
shell scripts. They serve as examples of the calc language and may also be
useful in themselves.
