INTRO="""Welcome to TwitterCmd, a command line interface to twitter,
written in Python. TwitterCmd provides a simple, interactive
interface to Twitter with short, easy to remember commands.

For a full set of commands, type "help" on the prompt.
For help for a specific command try "help <cmd>".

Please send comments/bug reports to <abpillai at gmail dot com>                   
or tweet them to the ID 'pythonhacker'.

The following commands are available.

User commands

1. l <user> <passwd> - Set login credentials.
2. u <user>          - Get details of a user.
3. f                 - Get friend's details.
4. fo                - Get followers' details.

Timeline commands

1. pt                - Get public timeline.
2. ut [<user>]       - Get current user timeline
                       (given no arguments), or
                       timeline of given user.
3. ft                - Get all friends' timeline.

Message commands

1. m <msg>           - Post a status message.
2. im <user> <msg>   - Post a direct message to user.
3. r                 - Get replies to messages.
4. dm                - Get all direct messages.

You can also use the 'inspect' or 'i' command to
inspect live objects. The following object types are
supported as argument.

1. s/status          - Inspect current msg status.
2. f/p/friends/peers - Inspect current friends status.
3. t/tl/tline        - Inspect current timeline.
4. u/user            - Inspect current user.

Version 0.2 also adds the power of entering Python
prompt while keeping state intact. To enter Python
prompt use any of 'shell','py' or 'python' commands.


# Post a message
Twitter> l user pass
Twitter> m Hey, I love twitter! 

# Get direct messages
Twitter> dm
["'No problem. :-)' => dloss"]

# Get names of all friends

To exit a session, type q/quit/exit or Ctrl-D.
