# Extending GPSMan: Plug-ins

GPSMan can be extended through pre- and user-defined plug-ins that are written in Tcl/Tk and are launched from either buttons and/or menu entries. In order to define a plug-in knowledge of programming in Tcl/Tk is required, while in some cases an understanding of parts of the GPSMan code might also be needed. This chapter is written assuming these prerequisites.

- The graphical interface for plug-in definitions
- Plug-in widgets
- Plug-in code and execution
- Pre-defined plug-ins
