+You can use this software under the terms of the GPL. If we meet some day,
+and you think this stuff is worth it, you can buy me a beer in return.
+
+Thanks to md for this useful formula. Beer is beer.
+
+Gets news article and sends it via SMTP.
+
+class news2mail is hopefully conform to rfc822.
+
+normal (what pygs does) operations flow is:
+1) reads from stdin NNTP article (readfile)
+2) divide headers and body (parsearticle)
+3) merges NNTP and SMTP heads into a unique heads
+4) adds, renames and removes some heads
+5) sorts remaining headers starting at top with Received: From: To: Subject:
+    Date:, normal headers ending with X-* and Resent-* headers.
