[[...]] Mailing Online [http://mol.usps.gov] and NetPost [http://www.usps.gov/netpost/] are apparently Tcl applications. ----- Actually, I think only Mailing Online is Tcl. See [COMPANY: BAE Systems, Business Systems Group (BSG)]. http://mol.usps.com runs [AOLserver]. ---- Mailing Online (MOL) is one component of the USPS NetPost program. 99% of MOL is TCL - this includes the web server [AOLserver], the backend processing, and the print site formating and control. The other 1% is VB ( :-( used to control some MS apps ) and 'C' wrappers to third party packages. I know this info to be accurate - I [mailto:jrohr@bellatlantic.net] designed the systems and wrote a large portion of it for BAE Systems. ---- [TclMML] is a Tcl package to interface with Mailing Online via the ''Mail Management Language'' (XML dialect). <> Company
