Eclipse's documentation
      
      We recommend the following configuation options:
      
	- 
	    Window -> Preferences -> Java -> Compiler:
	    
 set "Compiler compliance level" to 6.0
- 
	    Window -> Preferences -> General ->  Editors -> Text Editors:
	    
 select "Show line numbers"
- 
	    Window -> Preferences -> General ->  Web Browser:
	    
 set "Use external Web browser" with /usr/bin/firefox
- 
	    Window -> Preferences -> General ->  Appearance -> Colors and Fonts:
	    
 To change the default font size, select Basic -> Text Font and then click "Change".
- 
	    The default is that Eclipse automatically tries to build
	    projects whenever saved.  For now, I prefer to work
	    without this option.  It can be deselected as
	    Project -> Build Automatically.
	    After this point, the specific project can be built
	    manually using 
	    Project -> Build Project.
	
- 
	    EMACS users:  You can activate most typical emacs
	    key binding (e.g., Ctrl+A for beginning of line) by going to
	    Window -> Preferences -> General ->  Keys
	    and selecting "Emacs" from the pulldown menu for "Scheme".
	
      To create a new project, select
      File -> New -> Project  and select "Java Project".
      Give a project name (this may be different from the underlying
      filename for the project).  Then select from either creating a
      new project in your default workspace or from creating a project
      from an existing source.  At this point go ahead and "Finish"
      the setup.
      
      
      To run a program, select  Run -> Run at
      which point you are asked for what kind of project this is.
      Select "Java Application".  Then you can identify the Main
      class.  Once you've set up the configuration for your project,
      future runs can be done using the
      Run -> Run Last Launched option.
