	Sources	Mark a folder as a source root. Such folder displays in the list of source roots. If a folder is marked as a source root, it will be added to `PYTHONPATH`, and resolve will be performed against it. This command is duplicated from the context menu of a content root.
	Excluded	Mark a folder as an excluded root. Excluded roots are not visible to PyCharm. Usually, one would like to exclude temporary build folders, generated output, logs, and other project output. Excluding the unnecessary paths is a good way to significantly improve performance. This command is duplicated from the context menu of a content root.
