Re: [Mathlib-develop] JMathLib installation

[Stefan M. <st...@he...>]

Dear BB,
i just read your email.

As it turns out the documentation is really old regarding manual 
starting of JMathLib.

The part about starting has been written when JMathLib was still
called MathLib.

There are acutually two GUIs in JMathLib 0.9.0.
One is a conservative AWT and one is a swing type.

from the main directory:

java -cp bin jmathlib.ui.awt.GUI

or

java -cp bin jmathlib.ui.swing.SwingGUI

I just committed the documentation change to SVN.


Could you please supply the "start" file for Linux? (I am no linux user, 
windows only)

Kind regards,
   Stefan.
