+PORTING DETAILS
+by Simos Xenitellis <simos@hellug.gr>
+
+This program has been modified to compile with RedHat 6.1.
+It will possibly compile with other modern variants of Linux.
+In case of errors, edit the Makefile and cert_extract.c.
+The sections that may need to be customised are denoted.
+
+Copy your browsers' cert7.db to the working directory of this application
+with 
+	cp ~/.netscape/cert7.db .
+
+To run, type
+	
+	make
