%description

%{pkgname} (ESS) is an add-on package for GNU Emacs and XEmacs.  
It provides Emacs-based front ends for popular statistics packages.

ESS provides an intelligent, consistent interface between the user and
the software.  ESS interfaces with S-PLUS, R, SAS, BUGS and other
statistical analysis packages under the Unix, Microsoft Windows, and
Apple Mac OS operating systems.  ESS is a package for the GNU Emacs
and XEmacs text editors whose features ESS uses to streamline the
creation and use of statistical software.  ESS knows the syntax and
grammar of statistical analysis packages and provides consistent
display and editing features based on that knowledge.  ESS assists in
interactive and batch execution of statements written in these
statistical analysis languages.

This package contains the files common to both the GNU Emacs and
XEmacs %{pkgname} packages.
