I am new to the Java language and recently downloaded an API called
JExcel which will help you create MS Excel files. In the tutorial it
gives you an example on how to compile the downloaded file, but I'm
having a little trouble with it. The directions say to:

From the command line issue the following sequence of commands
(modifying file separators and classpath separators as required for
the target operating system):

javac -d out -classpath out:../src ../src/jxl/demo/*.java
jar cmf jxl.mf ../jxl.jar -C out common jxl

-can anyone explain to me what the directives are after the compiler
is called in order for me to change it?
