 # A wrapper around Nagios plugins that provides a URL link in the output

+#
+# Pay close attention to quoting to ensure that the shell passes the
+# expected data to the plugin. For example, in:
+#
+#    urlize http://example.com/ check_http -H example.com -r 'two words'
+#
+# the shell will remove the single quotes and urlize will see:
+#
+#    urlize http://example.com/ check_http -H example.com -r two words
+#
+# You probably want:
+#
+#    urlize http://example.com/ \"check_http -H example.com -r 'two words'\"
