-Provides an importer for Microsoft Windows monitor descriptions
-
-The code can be used as a python module for or as a script to add new monitor
-definitions to a monitor database.
-
-In code example: Read the list of monitors from an inf file.
-
-import infimport
-monitors = infimport.get_monitors_from_inf(PATH)
-
-Script example: To check for monitors of an inf file that are not yet in the database.
