MATE can be augmented by Python scripting, very similar to the Section 4.8, “User Scripts” in MeVisLab. For the scripting API, please refer to the MATE and the MATEDocument scripting references.

In addition to the user scripts, MATE can also execute a startup script. To edit that script, choose Edit MATE Startup Script File from the Extras menu.

Other than that, own user scripts for MATE are just like the user scripts in MeVisLab. MATE comes with some predefined user scripts that manage SVN operations on files and directories, as well as implementing some string functions on text selections. Have a look at those scripts to learn more.
