I just read the JEdit.org homepage. I am really intriuged by this comment over there and also your recommendation: jEdit is a mature programmer's text editor with hundreds (counting the time developing plugins) of person-years of development behind it. Would you please point me to a good resource to learn more about JEdit for someone with Emacs/Vim background.
