+Usage: perl convert_to_epl.pl workdir savedir
+
+Recursively processes workdir to examine all of the text files and convert
+all perfectly formed instances of the SFL copyright notice into EPL notices.
+
+If a file is modified, the original is first copied to the corresponding place
+under savedir. 
+
+It is safe to rerun this script if it stopped for any reason, as no converted 
+SFL notice will ever match on the second run through.
