CDonkey

http://cdonkey.suche.org

An eDonkey client for linux, written in C.

Pros:

• including the eMule Protokoll
• Overnet capable
• stable
• fast (the programm)
• low mem and CPU usage
• Runs with the actual linux ed2k GUI's

Cons:

• Very Poor Command Line Controls and no help
• The GUI's dons't support Overnet.
• Very Uncomfortable
• The webpage is only in german afaik

Better then the original eDonkey2000 client, worse then mlDonkey. In my Opinion :) You may want to give it a try :)
