-# A thing that implements dxcluster 'protocol'
+# This is the DX cluster 'daemon'. It sits in the middle of its little
+# web of client routines sucking and blowing data where it may.
 #
-# This is a perl module/program that sits on the end of a dxcluster
-# 'protocol' connection and deals with anything that might come along.
-#
-# this program is called by ax25d and gets raw ax25 text on its input
+# Hence the name of 'spider' (although it may become 'dxspider')
