13. htmlSave-Editor
    Often I have wanted to save Java or other languages as html. There are several tools o­nline that does this, but many are commercial and they are cumbersome to use (you often have to cut and paste the java into a webpage). So I figured, Eclipse has the style information needed (and I want my style not someone elses style), why not just extract it and generate HTML directly from Eclipse editors. This plug-in adds a simple action o­n the file menu to save the active text editor as HTML.
