+	  The editline library (from BSD) provides generic line editing
+	  and history functions. It slightly resembles GNU readline.
+
+	  The official homepage is at:
+	  http://ftp.netbsd.org/pub/NetBSD/NetBSD-release-5-0/src/lib/libedit/
+
+	  Jess Thrysoee maintains an autotoolified package, which we use
+	  in Buildroot as it makes it much simpler than using the
+	  upstream sources which require pmake.
