BSG uses Tcl extensively in-house and on projects. At BSG they do something called ''hybrid-mail''. This means they take documents (mostly soft copy) and deliver them multiple ways (e.g. high volume printing/inserting & postage mail, email, fax). Their biggest Tcl use involved building the USPS mailing online system [http://mol.usps.com]. There is over 125k lines of Tcl driving the system (web site, document manipulation, scheduling, distribution, high volume printer controlling, postage mgmt, address standardization, mail prep and envelope inserting). -- [Todd Coram] [Category Company]
