XDM is the standard very minimalistic login/greeter program for the X Window System.
Some years ago, back when KDM, GDM, etc were brand new ideas, Nemo instead took a different tack and created some scripts to theme the XDM window - via the use of shell scripts and Xresources. This was "XDM themestuff"
XDM themestuff is very abandoned now - in that it has not updated or even looked at in years... Should anyone want the latest version made, please contact Nemo.
- 1.x series was released (basic theming)
- 2.x series made it to "late beta" (multi-resolution themes handled better)
- 3.x series was brainstormed ("XDM window manager" for addional functions at XDM window)
