Allow formulae to use __END__ For this to work the "running script" must be the formulae file. Making this so wasn't so hard, there is now an install.rb script which is included with the -r flag to the ruby executable. An at_exit handler calls the install function. Having the install logic in its own file made it feel like there was so much space that I added extra error handling. So there is something to be said for separating functionality out into its own files. Still the error handling sucks, we'll need to marshall the exception back to the bin/brew command. Which is another PITA. Still overall I think this will prove worthwhile. But if it doesn't we'll revert. As a first usage, you can put a diff after __END__ and return DATA from Formula::patches to make Homebrew aware of it.

Some subdirs and renames to aid homebrew n00bs The classes better reflect their contents. I'm sure this change may be contentious, but I am a sucker for trying to create source bases that are easy to get to grips with and easy to navigate. brewkit.rb is now a deprecated file.

ARGV.extend(HomebrewArgvExtension)
Rewrite of HOMEBREW_ folder locations This rewrite attempts to sort out where the Prefix, Cellar, and Repository are relative to the real and symlinked 'brew' command. Also included is a --config option which dumps all of these variables. Any top-level script must define a "BREW_FILE" that gives the path to brew as it exists in the path. 'brew' itself just uses __FILE__ and install.rb does a `which brew` (there may be a better way?) The Prefix is always relative to the location of brew as it exists in the path. Thus, whether or not /usr/local/bin/brew is a symlink or real file, the Prefix is always /usr/local. If you have brew in some other prefix, such as /nonstandard/bin/brew, then '/nonstandard/ will be managed by brew instead. The Repository, Cellar, and "Library/Homebrew" required code is always found relative to the "real" path or brew. If brew is a real file in /usr/local/bin/brew, then everything else will be found in /usr/local and we'll expect a /usr/local/.git Otherwise, we dereference brew's symlink and look for everything else relative to that path instead.

HOMEBREW_PREFIX = Pathname.new(BREW_FILE).dirname.parent # Where we link under

Determine the repo path in a symlink-friendly way. The Contributions/selflink.sh script does not symlink the .git directory, so 'brew update' will fail because the prefix (/usr/local/) is not a git repository. To determine the actual location of the git repo we can get the realpath of the Library (to expand any symlinks) and take the parent of that.

Add full version and build numbers to user agent Signed-off-by: Max Howell <max@methylblue.com> I adapted it slightly based on the user agent that Safari gives.
