[Pharo-users] Can Pharo meet all your computing needs?

Hi folks I've been playing with Pharo recently, and really enjoying writing some programs in the Pharo environment. As a result, I've been wondering if I can use Pharo the way I would use Emacs, as an environment for doing everything. For example, can I use Pharo to: * Send emails to this mailing list? * Use IRC? * Start Bash? * Read the Pharo documentation (e.g. Pharo By Example)? If these things do exist, how do I discover them? Is there a package manager I can use to find new tools I can use in Pharo?
