Installation paths - leamas/OpenCPN GitHub Wiki

General

Plugins are made up of four parts:

Dynamic libraries
Data files
Translations
Helper binaries.

The only mandatory part is the plugin dynamic library, many plugins is basically just this file + some translations.

All paths described here should be treated as read-only, even on platforms which does not enforce this. In particular, any file created by a plugin inside these directories might be removed or modified when a plugin is updated.
