Don't symlink, as multiple formula will install to this directory.

GNU GetText breaks eg. Ruby 1.9 builds, and some other formula I have been building too. But it is required by eg. glib. So to solve this we are going to by default not symlink gettext into the Homebrew prefix.

Formula that depend on GetText will have the gettext paths added to the brewing environment automatically. Neat.

The "brew gen" command doesn't seem to exist, changed to "brew create", which isn't otherwise mentioned

Don't delete it if it doesn't exist.

This way caveats and other warnings/errors don't appear connected to the Summary text.

Eg. sbin may be part of the formula, but that isn't in the default Mac PATH. Also will avoid bug reports for users who forget to amend their PATH and stick Homebrew somewhere different.

I didn't change the class name, it's clear from the context where it is used what it does. However when just looking at files to figure out the nature of Homebrew I believe in clear naming.

Otherwise funny names earn you points.

Having gone through our patches it's clear that p1 is more standard.

Also fixed a bug where returning DATA outside of an array would fail to patch.

Homebrew doesn't install to man, but if it's already there, we should indeed ignore it.

See Library/Contributions

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.

This change also eliminates the somewhat duplicate codepath if patches
returns and Array rather than a Hash.

I didn't commit it all, apologies. But I just can't read the sections nearly as easily if you indent private and protected. If it's a Ruby convention it frankly seems at odds with the rest of Ruby spacing conventions.

Ant is a Java-based build tool. In theory, it is kind of like Make, without
Make's wrinkles and with the full portability of pure Java code.

I squashed a number of commits here, and also replaced the use of nspr.prefix with HOMEBREW_PREFIX as in theory we are flexible with our requirement for dependencies, although with the limited build system that SpiderMonkey possesses this is difficult for us to achieve anyway…

Points to eg. Cellar/wget/var rather than Cellar/wget/1.1.5/var
