Customization files allow you to create a convenient front-end user interface to control how ERC checks are set in a Calibre LVS run. This
provides the end user with an easy way to determine if and how individual ERC checks or groups of ERC checks will be used in a given
LVS scenario. In this video will demonstrate how such an interface might be used in LVS and then show how to create the interface using Tcl
based commands in a customization file.
