Scripting Olex2
There are two different levels on which Olex2 can be scripted
The functionality of Olex2 can be extended on two levels: though macros and through python scripts.
Olex2 Macros
There is a simple macro language, where you can group common tasks (and also redefine commands!). The built-in macros will be extended (and replaced!) with those macros you will find in the file you will see when you type >>emf.
Python Scripts
You can also script Olex2 using Python. All functions of Olex2 can be accessed and highly complex functionality can be added.
