Sample .emacs file
This bundle provides the downloads for setting up Emacs with the latest Java Development (JDE) and also the latest Java-mode for Emacs. You do not need the latest version of Emacs to use JDE and the latest cc-mode. Note: version 5.26 of cc-mode is required for customizing the indentation. It is also recommended to byte-compile CC Mode, for both performance and compatibility reasons. Refer to the README in the cc-mode installation directory for details. The sample .emacs preferences file shows how to enable JDE, use spaces for tabs, control the indentation, removal of CTRL-M using a function-key, print and more is also provided.
