Description:

GNOME (GNU Network Object Model Environment) is a user-friendly set of
applications and desktop tools to be used in conjunction with a window
manager for the X Window System. GNOME is similar in purpose and scope
to CDE and KDE, but GNOME is based completely on free software.

This is the Gnumeric, the GNOME spreadsheet program. If you are familiar with
Excel, you should be ready to use Gnumeric. It tries to clone all of
the good features and stay as compatible as possible with Excel in terms of
usability. Hopefully the bugs have been left behind :).
