%description
The official Eclipse Installer (Oomph) lets you choose and install Eclipse IDE
packages in your home directory. This package includes Eclipse's bundled Java
runtime. IDE installations, workspaces, and the user's shared bundle pool are
managed separately from this RPM. Run the installer as a normal user, not root.
