# -*- coding: utf-8 -*- """KiCad Python Shell. This module provides the python shell for KiCad. Currently the shell is only available inside PCBNEW. PCBNEW starts the shell once, by calling makePcbnewShellWindow() the first time it is opened, subsequently the shell window is just hidden or shown, as per user requirements. IF makePcbnewShellWindow() is called again, a second/third shell window can be created. PCBNEW does not do this, but a user may call this from the first shell if they require.
