The package nntp provides a simple Tcl-only client library for the NNTP protocol. It works by opening the standard NNTP socket on the server, and then providing a Tcl API to access the NNTP protocol commands. All server errors are returned as Tcl errors (thrown) which must be caught with the Tcl catch command.



A bigger example for posting a single article.

Message-ID: <[pid][clock seconds]
