+This is a quick hack because I'm fed up of not having all the entries I
+want in my /etc/services file. Now I can drop my local mods in
+/etc/services.d and run update-services when they change. Easy.

+.TH merge-services 1 "29 April 2005"
+.SH NAME
+merge-services \- merge entries from several /etc/services files
+.SH SYNOPSIS
+.B merge-services
+.I file
+\&...
+.SH DESCRIPTION
+The
+.B merge-services
+command reads the services files given on the command line and writes a
+merged file to its standard output.
+.PP
+A services entry consists of five parts: a
+.IR name ,
+a
+.IR "port number" ,
+a
+.IR protocol ,
+a list of
+.IR aliases ,
+and a
+.IR comment .
+The merging process discards all comments. Two entries match if their
+names, ports and protocols are all equal: in this case, the output
+contains a single entry listing the union of both sets of aliases. In
+all other cases, entries are left alone.
+.SH BUGS
+It's very stupid.

+The

+merges the contents of the files in

+.PP
+To save Emacs users from going mental, it ignores files whose names end
+in

+or
