Renaming main method class.
When compiling my java classes, I find that they are always compiled
to a file name of X.class.
If I only ever want to rename one class file, the class file with my main method
inside it, and have
java NewClassName.newExtention
run it as per normal, may I do that, and how do I have it run?
What may I specify in an executable jar file's manifest main-class entry to have this work as well?
