How Should We Use Struct?

The Choice

It's common in Ruby to see some code setup a Struct like this:

class Specialized < Struct.new(:whatever)
  # ... define custom methods here...
end

What I believe is the most confusing thing for git beginners is that the main commands have multiple uses depending on the arguments or context, and some of those uses aren't well-described by the command's name.

Merge

merges together different branches (different histories, to be more exact)
fast-forwards if a merge isn't necessary; effectively repositioning the branch head to a descendant commit
unwanted outcome of git pull

Rebase

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
