 comment = "rpoll(3) interface for event-driven I/O"
+
 desc = <<EOD
 libbegemot provides rpoll(3), a simplified interface for handling event-driven
 I/O programming.
+
+Many programs need to read from several file descriptors at the same time.
+Typically in these programs one of select(2) or poll(2) is used.  These
+calls are however clumsy to use and the usage of one of these calls is
+probably not portable to other systems - not all systems support both calls.
+
+The rpoll(3) family of functions is designed to overcome these restrictions.
+They support the well known and understood technique of event driven programing
+and, in addition to select(2) and poll(2) also support timers.
