+
+Muscl is a CLI tool that let's unprivileged users perform administrative
+operations on a MySQL DBMS, given the are authorized to perform the action
+on the database or database user in question. The default authorization
+mechanism is to only let the user perform these actions on databases and
+database users that are prefixed with their username, or with the name of any
+unix group that the user is a part of. i.e. `<user>_mydb`, `<user>_mydbuser`,
+or `<group>_myotherdb`.
+
+The available administrative actions include:
+
+- creating/listing/modifying/deleting databases and database users
+- modifying privileges for a database user on a database
+- changing the passwords of the database users
+- locking and unlocking database users
+- ... more to come
+
+The software is designed to be run as a client and a server. The server has
+administrative access to the mysql server, and is responsible for authorizing
+any requests from the clients.
+
+This software is designed for multi-user servers, like tilde servers,
+university servers, etc.\
