WMI
wmi was the initial project which became popular, though wmii is the successor of wmi. The last release of wmi happened back in 2004. There are still some occasional users of wmi. If you like to check how the good old days felt, check it out, though its code sucks more unfortunately than our more recent projects.

Download
You can download the historic copy of wmi-10. Unfortunately there is no associated repository anymore. There used to be a subversion repository in the older days.
Build
In order to build wmi-10 on more recent systems than they were back 4 years ago, you will need to apply this patch by Sergey Dolgov.
Issues
If you want to contact the author of wmi, use his proper email address garbeam@gmail.com -- the email address presented in the wmi-10 source isn't valid anymore.
