jQuery did this for JS, we're doing it for zsh. Simplest zsh configuration framework ever. Based on the "Explicit is better than implicit" paradigm (is it one?) from the Zen of Python, so (almost) nothing gets loaded when you source the file.

It's a big ass thing which loads a lot of files → pretty slow on HDDs (don't worry, I have an SSD now!). I've got tired of it and made my own framework. You're looking at it now :)

• Checks: functions is_mac, is_linux, is_freebase, has_brew, has_apt, has_yum for your if statements (variables like IS_MAC are deprecated)
• Some common defaults
• Plug&play support for Ubuntu's command-not-found, hub, RubyGems on Debian/Ubuntu, rvm, rbenv, jump
• Prompt setting aliases (for better readability) and "prompts" command which just sets both left and right prompts
• Neat stuff for your prompt: virtualenv info, smart prompt character (by Steve Losh. ± when you're in a Git repo, ☿ in a Mercurial repo, $ otherwise), rvm/rbenv ruby version
• Aliases, including LOLSPEAK ones (loaded separately)
• Completion for a lot of stuff
• Correction
• Current directory in title support: add update_terminal_cwd to your chpwd(). In OS X Lion Terminal.app, this'll be draggable!

• last_modified pretty self-explanatory
• ex extract archives
• mcd mkdir + cd
• .., .... cd-ing .. and ../..
• beep
• pj pretty-print JSON
• cj curl and pretty-print JSON
• md5, sha1, sha256, sha512, rot13, rot47, urldecode, urlencode of a string
• gimme install packages (Homebrew on Mac OS X, apt/yum on Linux)
• pinst install python package from current dir and remove build, dist and egg-info folders
• s_http serve current folder via http
• s_smtp launch an SMTP test server for development, on port 1025
• lst ls tree-style
• up find a file in parent dirs
• path pretty-print $PATH (with colors! yay!)

• vol get/set sound volume
• locatemd search with Spotlight
• ql open something in Quick Look
• oo open current dir in Finder
• cdf cd to the current path of the frontmost Finder window
• pman open man pages in Preview
• mailapp creates a message in Mail.app from the first arg as a string or stdin if there are no args (eg. you can pipe stuff into it)
• sparrow same for Sparrow.app
• evernote same with a note in Evernote.app
• quit, relaunch OS X GUI apps
• selected Finder items
