+  **** DEVELOPMENT INFORMATION ****
+
+  I want to ask how cross posting to multiple lists are handled. For example:
+  User posts to the following two lists which are both mail to news gateways:
+  listone@lists.org -> lists.listsone
+  listtwo@lists.org -> lists.listtwo
+  Obviously both messages will have an identical Message-ID header of which
+  nntp will reject one of the two posts. Ideally this would be caught and
+  the message would be cross posted to both lists.listsone and lists.listtwo
+  groups.
+
+  Proposal for using -h Newsgroups:${To:s/SEARCH/REPLACE/} with SEARCH/REPLACE
+  being the following regex:
+      perl -e '$_="foo\@bar\nFoo Bar <foo\@bar>\nfoo\@bar (Foo Bar)\n<foo\@bar> Foo Bar\n(Foo Bar) foo\@bar\n";
+      foreach $a (split(/\n/, $_)) { $n=$a;
+      $n=~s/^(?:([^@<>()]+)@[^<>()]+|.*<([^@]+)@[^>]+?>.*|.*?([^@ <>()]+)@[^ <>()]+.*)$/$1$2$3/;
+      print "$a->$n\n" };'
+  1.) OSSP var needs autoconf environment
+  2.) OSSP var needs RPM-style [] multivalue expansion
+  3.) include OSSP var 
+  4.) splitting headers needs to extend known headers into multiple instances
+  5.) joining headers needs to merge known headers into single instances, delete headers w/o value
+  6.) add -f configfile option in a mini-library #comments, command[\svalue]
+  Result is:
+    duplicate Reply-To: headers are eleminated by 5.)
+    empty Subject: headers can be handled by      -h Subject:${Subject:-empty}
+    missing Message-Id: headers can be handeld by -h Message-Id:${Message-Id:-$_CreateMessageId}
+    illegal Message-Id: two or more @ use         -h ${Message-Id:s/^.*@.*@.*$/$_CreateMesssageId/}
+    illegal Message-Id: no @ use                  -h ${Message-Id:s/^[^@]*$/$_CreateMesssageId/}
+    crossposting problem                          -h [Newsgroups:see perl example above and use feature 2.)\n]
+    potential to merge post/header modes          -h [Newsgroups:${_EnvelopeRCPT}\n]
