Thanks for the feedback. I'll update the readme.txt to use the --package
option.

This is most likely because you used the JRE to install Jython. The JRE
does not include a java compiler.

If the JRE is the only JVM you have installed, you will need to install
the full JDK. If you have installed the full JDK already, you may need
to specify the full path to the JDK java.exe when installing Jython, ie:

   c:\java\jdk1.3\bin\java -cp . Jython-20a1

where c:\java is the path you specified when you installed the JDK.

I have very recently added additional information to the install.html
page which hopefully will help other from falling into the same
problems.
