Noooo, not another Twitter client! Yes, another Twitter client. The difference here is that you're dealing with a multi-functional, fully 100% text, Perl command line client.

* In interactive mode, it is a fully interactive client with asynchronous background updates and commands. Use it over telnet, ssh or even a dummy terminal.
* From the command line, use it to update your Twitter in shell scripts, from the command line, from cron, and so on.
* Supports standard timelines and automatically fetches direct messages.
* Extensible using the -lib option.
* Run detached in -daemon mode, and make your own Twitter bot!

ttytter requires Perl 5.005 or better, and either curl or Lynx (chosen on purpose since more people are likely to have one or both of those instead of LWP, and also to allow people to carry over their proxy settings and whatnot). Nothing else is necessary; it does not use Net::Twitter and does not require it. It will work fine over any dummy terminal, serial connection or telnet/ssh login. ttytter is offered as freeware under the Floodgap Free Software License.
