There are two types of addons:
 * 1) Macros: short snippets of Python code that provide a new tool or functionality. Macros usually start as a way to simplify or automate the task of drawing or editing a particular object. If many of these macros are collected inside a directory, the entire directory may be distributed as a new workbench.
 * 2) External workbenches: collections of tools programmed in Python or C++ that extend FreeCAD in an important way. If a workbench is sufficiently developed and is well documented, it may be included as one of the base workbenches in FreeCAD. Under External workbenches, you'll find the principle and a list of existing library.
