 # libesmtp
 
+LibESMTP is a library to manage posting (or submission of) electronic mail using SMTP to a
+preconfigured Mail Transport Agent (MTA) such as Exim. It may be used as part of a Mail User
+Agent (MUA) or another program that must be able to post electronic mail but where mail
+functionality is not the program's primary purpose.
