Manipulate Dalvik eXchange format and produce dex files

 Dalvik is a process virtual machine in Google's Android operating system that
 executes applications written for Android.
 .
 dalvik-exchange is the tool that takes in class
 files and reformulates them for consumption in the VM. It also does a few other
 things.
 .
 This program is officially named "dx" but in order to avoid naming conflict
 with OpenDX in Debian it is renamed to "dalvik-exchange".
 .
 This package also provides the "mainDexClasses" program.
