+This application provides a dyndns server style updater for using webfaction domain as dyndns.
+the url to be used in updating is as follows
+http://[USERNAME]:[PASSWORD]@tanshu.com/update?hostname=[DOMAIN]
+or with custom ip address
+http://[USERNAME]:[PASSWORD]@tanshu.com/update?hostname=[DOMAIN]&ip=[IP]
+The users are maintained in the .htpasswd file in the production.ini directory.
+The way to add/update users is "htpasswd .htpasswd [USERNAME]
+the domains should be in the "dns_info" file in the format "domain:ipaddress"
+The location of both the files can be changed in the ini file.
+Also, the webfaction username and password needs to be configured in the ini file.
