// This script was designed to run in ColdFusion Studio 5.
// It removes extra white space characters, removes comments, and runs a customized CodeSweeper on an HTML table.
//
// This script is provided without warranty.
// This script is the first in a series of four scripts that are provided to show logic that can be used to help automate the tagging of tables for Section 508 compliance.
// Individual solutions will vary based on source program generating the HTML, table structure, and CSS coding.
// Please include appropriate attribution in any future work based on these scripts.
