 ```
 Use `script/gemfile local` to get at the local ones, and `script/gemfile remote` to get at the remote ones.
 It then runs `bundle install`.
 You can also run `penchant gemfile ENV`. Just straight `penchant gemfile` will rebuild the `Gemfile` from
 `Gemfile.penchant` for whatever environment the `Gemfile` is currently using.
 If you have an existing project, `penchant convert` will convert the `Gemfile` into a `Gemfile.penchant`
 and add some bonuses, like defining that anything in `env :local` blocks automatically reference `..`,
 ensuring that hooks are always installed when `penchant gemfile` is executed, and adding the `:github` gem property
 that lets you pass in the username of the repo to reference that repo:
 `gem 'penchant', :github => 'johnbintz'`.
 ### Stupid-simple local/remote setup
 Use `opposites :local, :remote` and environment settings for local/remote gems will be set accordingly depending
 on environment:
 ``` ruby
 defaults_for env(:local), :path => '../%s'
 opposites :local, :remote
 env :remote do
  gem 'my-gem', :git => 'git://github.com/johnbintz/my-gem.git'
 end
 ```
 In `remote`, the Git repo version is used. In `local`, the path is used. Only one gem definition needed!
 ### Deployment mode
 Use `no_deployment` blocks to indicate gems that shouldn't even appear in `Gemfiles` destined for
 remote servers. *Very* helpful when you have OS-specific gems and are developing on one platform
 and deploying on another, or if you don't want to deal with the dependencies for your testing
 frameworks:
 ``` ruby
 gem 'rails'
 no_deployment do
  os :darwin do
    gems 'growl_notify', 'growl', 'rb-fsevent'
  end
  os :linux do
    gem 'libnotify', :require => nil
  end
  group :test do
    # ... all your testing libraries you won't need on the deployed end ...
  end
 end
 ```
 Run `penchant gemfile ENV --deployment` to get this behavior. This is run by default when the
 pre-commit git hook runs, but only after the default Rake task passes.
 If you just want any locally installed gems, add the `--local` switch. Great if rubygems.org is down!
 #### Won't this change the project dependencies?!
 Probably not. You probably have the "main" gems in your project locked to a version of Rails or
 Sinatra or something else, and all of the other gems for authentication, queue processing, etc. are
 dependent on that framework. Ripping out your testing framework and deployment helpers really
 shouldn't be changing the main versions of your application gems. It WORKSFORME and YMMV.
 ### Getting local gems all set up
 `penchant bootstrap` will go through and find all git repo references in your `Gemfile.penchant` and
 will download them to the specified directory (by default, `..`). This means blocks like this
 will work as expected when you `penchant bootstrap` and then `penchant gemfile local`:
 ``` ruby
 env :local do
  gem 'my-gem', :path => '../%s'
 end
 env :remote do
  gem 'my-gem', :git => 'git://github.com/johnbintz/%s.git'
 end
 ```
 Note that this just does a quick `git clone`, so if your project is already in there in a different state,
 nothing "happens" except that git fails.
 ## initialize-environment
-Get new developers up to speed fast! `script/initialize-environment` does the following when run:
+It will also try to run `rake bootstrap`, so add a `:bootstrap` task for things that should happen when you start going
 (make databases, other stuff, etc, whatever).
-* Check out any remote repos found in `Gemfile.penchant` to the same directory where your current project lives.
+## Gemfile.erb?!
  That way, you can have your `Gemfile.penchant` set up as above and everything works cleanly.
 * Runs `script/gemfile remote` to set your project to using remote repositories.
 * Runs `rake bootstrap` for the project if it exists.
-### After-`gemfile` hooks?
+Yeah, it's a `Gemfile` with ERB in it:
-Drop a file called `.penchant` in your project directory. It'll get executed every time you switch environments using
+``` erb
-Penchant. I use it to tell my Hydra clients to sync and update their Gemfiles, too:
+<% if env == "local" %>
-
+  gem 'guard', :path => '../guard'
-``` ruby
+<% else %>
-# rake knows if you need "bundle exec" or not.
+  gem 'guard', :git => 'git://github.com/johnbintz/guard.git'
-
+<% end %>
 rake "hydra:sync hydra:remote:bundle"
 ```
-### What environment are you currently using in that Gemfile?
+Use `script/gemfile local` to get at the local ones, and `script/gemfile remote` (or anything, really) to get at the remote ones.
-
+It then runs `bundle install`.
 `head -n 1` that puppy, or `penchant gemfile-env`.
 ## git hook?!
-It runs `penchant gemfile remote` then runs `bundle exec rake`. Make sure your default Rake task for the project runs your

 to your commit if they've changed.
 ### Ensuring git hooks get installed
 I find that when I pull down new projects I never remember to install the git hooks, which involves an awkward running
 of `bundle exec rake` *after* I've already committed code. Since we have computers now, and they can be told to do things,
 you can add `ensure_git_hooks!` anywhere in your `Gemfile.penchant` to make sure the git hooks are symlinked to the ones
 in the `script/hooks` directory with every processing of `Gemfile.penchant`.
 ### Performing pre-`bundle exec rake` tasks.
 Example: I use a style of Cucumber testing where I co-opt the `@wip` tag and then tell Guard to only run scenarios with `@wip` tags.
 I don't want `@wip` tasks to be committed to the repo, since committing a half-completed scenario seems silly.
 So I use `bundle exec rake preflight_check` to check all feature files for `@wip` tasks, and to fail if I hit one. Yes, Cucumber
 already does this, but in order to get to `bundle exec rake`, I need to go through two `Gemfile` creations, one for `remote --deployment`
 and one for `remote` to make sure my tests work on remote gems only.
 If `bundle exec rake -T preflight_check` returns a task, that task will be run before all the `Gemfile` switcheroo. *Don't use it
 as a place to run your tests!*
 ### Skipping all that Rake falderal?
 Do it Travis CI style: stick `[ci skip]` in your commit message. That's why the meat of the git hooks resides in
 `commit-msg` and not `pre-commit`: you need the commit message before you can determine if the tests should be run
 based on the commit message. Weird, I know.
 ## How?!
-* No RVM? `gem install penchant`
+* `gem install penchant`
 * RVM? `rvm gemset use global && gem install penchant && rvm gemset use default`
 * `cd` to your project directory
-
+* `penchant install` (can do `--dir=WHEREVER`, too)
 And then one of the following:
 * `penchant install` for a new project (`--dir=WHEREVER` will install the scripts to a directory other than `$PWD/scripts`)
 * `penchant update` to update the installation (`--dir=WHEVEVER` works here, too)
 * `penchant convert` for an existing project (`--dir=WHEVEVER` works here, too)
