title: How to create my own button for the Eclipse tool-bar?
body: <p>I am assuming this falls under plug-in development, but I am unsure.</p>
  
  <p>Are all things in Eclipse(e.g. a button), plug-ins?</p>
  
  <p>Is it possible to look at source code of a button (e.g. the resume/step/pause button)?</p>
  
  <p>I am very interested in how these buttons interact with GDB and what hooks there are for remote debugging, I am assuming via the GDB remote serial protocol.</p>
