__title__="FreeCAD Parts Library Macro"
__author__ = "Yorik van Havre"
__url__ = "http://www.freecadweb.org"

'''
FreeCAD Parts Library import macro

INSTALLATION

This script is made to be used as a FreeCAD macro, and to be placed
inside your macros folder (default is $HOME/.FreeCAD on mac/linux, 
C:/Users/youruser/Application Data/FreeCAD on windows).

You must also edit this file and change the configuration line below 
to reflect the location of your FreeCAD-library folder.

After it is installed on the above location, it will be available
in the macros menu.

USAGE

This macro adds a browser window to the FreeCAD interface, from
which you can browse and install items from the library.
'''

# CONFIGURATION - EDIT THE FOLLOWING LINE TO MATCH YOUR LIBRARY PATH
LIBRARYPATH = "/home/yorik/Sources/FreeCAD-library"
# END CONFIGURATION - THAT'S DONE, NO NEED TO EDIT ANYTHING MORE
