{ The primary config path is the local or user specific path.
If the primary config path does not exist, it will automatically be
created by the IDE.
The secondary config path is for templates. The IDE will never write to it.
If a config file is not found in the primary config file, Lazarus will
copy the template file from the secondary config file. If there is no
template file, the IDE will use defaults.
