+rebar
+=====
+
+rebar is an Erlang build tool that makes it easy to compile and
+test Erlang applications, port drivers and releases.
+
+rebar is a self-contained Erlang script, so it's easy to distribute or even
+embed directly in a project. Where possible, rebar uses standard Erlang/OTP
+conventions for project structures, thus minimizing the amount of build
+configuration work. rebar also provides dependency management, enabling
+application writers to easily re-use common libraries from a variety of
+locations (git, hg, etc).
+
+Building
+--------
+
+Information on building and installing Erlang/OTP can be found
+in the `INSTALL.md` document.
+
+### Dependencies
+
+To build rebar you will need a working installation of Erlang R13B03 (or
+later).
+
+Should you want to clone the rebar repository, you will also require git.
+
+#### Downloading
+
+Clone the git repository:
+
+    $ git clone git://github.com/basho/rebar.git
+
+#### Building rebar
+
+    $ cd rebar/
+    $ ./bootstrap
+    Recompile: src/getopt
+    ...
+    Recompile: src/rebar_utils
+    ==> rebar (compile)
+    Congratulations! You now have a self-contained script called "rebar" in
+    your current working directory. Place this script anywhere in your path
+    and you can use rebar to build OTP-compliant apps.

+Indentation
+-----------
+
+To have consistent indentation we have vi modeline/emacs local variable  
+headers in rebar's source files. This works automatically with vi.  
+With Emacs you have to declare <code>'erlang-indent-level</code>
+set to <code>4</code>  
+as a safe local variable value. If not configured Emacs will prompt  
+you to save this as part of custom-set-variables:
+
+    '(safe-local-variable-values (quote ((erlang-indent-level . 4))))
+You can also tell Emacs to ignore file variables:
+
+    (setq enable-local-variables nil
