+pry-git
+===========
+
+(C) John Mair (banisterfiend) 2011
+
+_ruby aware git_
+
+Retrieve blame, perform diffs, make commits using the natural units of
+Ruby code.
+
+pry-git enables you to diff an individual _method_ , it can show you
+the blame for a method  and ultimately allow you to commit 'methods' (rather than amorphous
+'hunks' of code).
+
+pry-git is a plugin for the [pry](http://github.com/banister/pry)
+REPL, a powerful IRB alternative.
+
+pry-git is very much proof of concept right now, stay tuned!
+
+* NOT AVAILABLE: Install the [gem](https://rubygems.org/gems/pry-git): `gem install pry-git`
+* NOT AVAILABLE: Read the [documentation](http://rdoc.info/github/banister/pry-git/master/file/README.md)
+* See the [source code](http://github.com/banister/pry-git)
+
+Example: blame
+--------
+
+    pry(main)> blame Pry#repl
+    John Mair   def repl(target=TOPLEVEL_BINDING)
+    John Mair     target = Pry.binding_for(target)
+    John Mair     target_self = target.eval('self')
+    John Mair
+    John Mair     repl_prologue(target)
+    Mon ouïe
+    John Mair     # cannot rely on nesting.level as
+    John Mair     # nesting.level changes with new sessions
+    John Mair     nesting_level = nesting.size
+    John Mair
+    John Mair     break_data = catch(:breakout) do
+    John Mair       nesting.push [nesting.size, target_self, self]
+    John Mair       loop do
+    John Mair         rep(target)
+    John Mair       end
+    John Mair     end
+    John Mair
+    John Mair     return_value = repl_epilogue(target, nesting_level, break_data)
+    Lee Jarvis    return_value || target_self
+    John Mair   end
+
+Example: diff
+--------
+
+    pry(main)> diff Pry#repl
+       def repl(target=TOPLEVEL_BINDING)
+    +
+    +    # hey baby
+         target = Pry.binding_for(target)
+         target_self = target.eval('self')
+
+    +    # bink
+         repl_prologue(target)
+
+         # cannot rely on nesting.level as
+         # nesting.level changes with new sessions
+         nesting_level = nesting.size
+
+         break_data = catch(:breakout) do
+           nesting.push [nesting.size, target_self, self]
+           loop do
+             rep(target)
+           end
+         end
+
+         return_value = repl_epilogue(target, nesting_level, break_data)
+         return_value || target_self
+       end
+    -
+    -  # Perform a read-eval-print.
+    -  # If no parameter is given, default to top-level (main).
