= Configlet

* http://github.com/jbarnette/configlet

== Description

A stupid simple wrapper for environment variables.

This doesn't deserve to be released as a gem, but I'm using it in two
different projects. Seriously, go find a real configuration library
and use it instead.

== Examples

    require "configlet"

    # assuming...
    ENV["THUNK_STATUS"]   = "crazy-awesome"
    ENV["THUNK_FINISHED"] = "false"

    # some bits of optional config
    Configlet.prefix = :thunk
    Configlet.default :token => "default-token"
    Configlet.munge(:finished) { |k| "true" == k }

    # grabbin' values
    Configlet[:status]   # => "crazy-awesome"
    Configlet[:finished] # => false
    Configlet[:token]    # => "default-token"

There's also a block form, which is nice if you're setting a lot of
defaults:

    Configlet.for :thunk do
      default :token => "default-token"
      default :host  => "thunk.local"
    end

Configlet is a module, so +include+ or +extend+ it wherever you
want. It extends itself for your convenience.

== Installation

    $ gem install configlet
