// Purpose:

// Description: Header file for ecConfigItem, which describes a config item

//              from this tool's perspective. Note that this duplicates

//              some of the CDL data structures in order to be able to test the

//              UI independently; we may eliminate some of the duplication later.

// Requires:

// Provides:

// Known bugs:

// Usage:
