Having failed to compile Mule on Linux I was fortunate to discover that a precompiled version is already available to Linux users. All you need do is download 7 files. Below is what I believe is the minimalist approach for getting a basic Mule running.
You have mule installed, you can start it with ``mule-19.28'' But you are not ethiopic ready, so lets get the fonts:
Now start Mule with mule-19.28 ( you may want to alias or rename the command later ). Since we didn't compile this ourselves with Ethiopic as the default, we need to start it each time we run Mule.
You should see the word [IPA] turn into [(fi)(de)(l)]
Through the "Help" menu instructions can be found by following:
Info / Mule / Languages / Ethiopic
To choose menu items in the page you will need the middle mouse button -or three button emulation on for 2 button mice. Of course, one of my favorite web sites also has the the instructions for Ethiopic on-line ;-) The rest is a matter of coolizing your .emacs file.
