+# Two options to enable readline compatible libraries: 
+#
+#   --enable-editline
+#   --enable-readline
+#
+# Both are enabled by default. If, after command line processing both are
+# still enabled, the script searches for editline first and automatically
+# disables readline if it is found. So, to use readline explicitly, the
+# user must pass "--disable-editline". To disable command line editing
+# support altogether, "--disable-editline --disable-readline".
+#
+# When searching for either library, check for headers before libraries 
+# as some distros supply packages that contain libraries but not header
+# files, which come as a separate development package.
