This is a java compilator, which will allow you to combine two java programs (midlets) into one jar file and execute them as one application on the phone.

This is a command line software and the usage is simple:
> mm.cmd  midlet1.jar midlet2.jar -r supermidlet.jar
That will combine midlet1.jar and midlet2.jar into one jar and jad file called supermidlet.jar.

Folder structure:
midplib/
 midp libraries
multime/
 the midlet manager itself
output/
 here by default we will store the ready midlets
preverify/
 verificator
temp/
 temporary folder
mm.cmd
 the program executor
mm.jar
 own constructor

For more detailed instructions just typw mm.cmd with no parameters in the command prompt. Most of the features are self explanatory

After the midlet is ready the usage is simple - you will start it on the phone and you will see a list with programs. Choose "Run" and the midlet should start. Additionally there is a new function inside called Minimize, which will let you start the other midlet(s) simulatenously
