26 External jar libraries and jython macros

If you want to include some external libraries in jar form, just put them in the ``lib'' directory. Next time when you run ``jhepwork.sh'' (or ``jhepwork.bat'' for Windows) script, your external classes should be available for Jython/BeanShell. Please look at the Section :autorefsection6 to learn how to compile jar libraries.

The user jython macros should be put to the ''macros/user'' directory. You can add some other directory visible for jython import statement in the initialization file ''macros/system/jehepsys.py''.
