+.SH HISTORY
+.IX Header "HISTORY"
+\&\f(CW\*(C`Sys::Syslog\*(C'\fR is a core module, part of the standard Perl distribution
+since 1990.  At this time, modules as we know them didn't exist, the
+Perl library was a collection of \fI.pl\fR files, and the one for sending
+syslog messages with was simply \fIlib/syslog.pl\fR, included with Perl 3.0.
+It was converted as a module with Perl 5.0, but had a version number
+only starting with Perl 5.6.  Here is a small table with the matching
+Perl and \f(CW\*(C`Sys::Syslog\*(C'\fR versions.
