+pathogen.vim
+============
+
+Manage your `'runtimepath'` with ease.  In practical terms, pathogen.vim
+makes it super easy to install plugins and runtime files in their own
+private directories.
+
+Installation
+------------
+
+Install to `~/.vim/autoload/pathogen.vim`.  Or copy and paste:
+
+    mkdir -p ~/.vim/autoload ~/.vim/bundle
+    curl https://raw.github.com/tpope/vim-pathogen/HEAD/autoload/pathogen.vim \
+      > ~/.vim/autoload/pathogen.vim
+
+If you don't have `curl`, use `wget -O -` instead.
+
+By the way, if you're using Windows, change all occurrences of `~/.vim`
+to `~\vimfiles`.
+
+Runtime Path Manipulation
+-------------------------
+
+Add this to your vimrc:
+
+    call pathogen#infect()
+
+If you're brand new to Vim and lacking a vimrc, `vim ~/.vimrc` and paste
+in the following super-minimal example:
+
+    call pathogen#infect()
+    syntax on
+    filetype plugin indent on
+
+Now any plugins you wish to install can be extracted to a subdirectory
+under `~/.vim/bundle`, and they will be added to the `'runtimepath'`.
+Observe:
+
+    cd ~/.vim/bundle
+    git clone git://github.com/tpope/vim-fugitive.git
+
+Now [fugitive.vim](https://github.com/tpope/vim-fugitive) is installed.
+If you really want to get crazy, you could set it up as a submodule in
+whatever repository you keep your dot files in.  I don't like to get
+crazy.
+
+If you don't like the directory name `bundle`, you can pass a different
+name as an argument:
+
+    call pathogen#infect('stuff')
+
+You can also pass an entire path instead.  I keep the plugins I maintain
+under `~/src`, and this is how I add them:
+
+    call pathogen#infect('~/src/vim/bundle')
+
+Normally to generate documentation, Vim expects you to run `:helptags`
+on each directory with documentation (e.g., `:helptags ~/.vim/doc`).
+Provided with pathogen.vim is a `:Helptags` command that does this on
+every directory in your `'runtimepath'`.  If you really want to get
+crazy, you could even invoke `Helptags` in your vimrc.  I don't like to
+get crazy.
+
+Finally, pathogen.vim has a rich API that can manipulate `'runtimepath'`
+and other comma-delimited path options in ways most people will never
+need to do.  If you're one of those edge cases, look at the source.
+It's well documented.
+
+Runtime File Editing
+--------------------
+
+As a guy who writes a lot of Vim script, I edit a lot of runtime files.
+For example, when editing a PDF file like I do every day, I might notice
+something weird in the syntax highlighting and want to have a look:
+
+    :sp $VIMRUNTIME/syntax/pdf.vim
+
+Even the best case scenario with tab complete is painful:
+
+    :sp $VIMR<Tab>/synt<Tab>/pd<Tab>
+
+The picture is even bleaker if the file in question sits in a
+bundle.  Enter the V family of commands.  The V stands for Vimruntime
+(work with me here).
+
+    :Vsp s/pd<Tab>
+
+As you can see, not only does it eliminate the need to qualify the
+runtime path being targeted, the tab completion is friendlier, allowing
+you to expand multiple components at once.  Here's me editing
+pathogen.vim itself:
+
+    :Ve a/pat<Tab>
+
+In the event of duplicate files, you can give a count to disambiguate.
+Here's the full list of commands:
+
+* `:Vedit`
+* `:Vsplit`
+* `:Vvsplit`
+* `:Vtabedit`
+* `:Vpedit`
+* `:Vread`
+
+There's also `:Vopen`, which is like `:Vedit` but does an `:lcd` to the
+containing runtime directory first.
+
+FAQ
+---
+
+> Can I put pathogen.vim in a submodule like all my other plugins?
+
+Sure, stick it under `~/.vim/bundle`, and prepend the following to your
+vimrc:
+
+    source ~/.vim/bundle/vim-pathogen/autoload/pathogen.vim
+
+> Will you accept these 14 pull requests adding a `.gitignore` for
+> `tags` so I don't see untracked changes in my dot files repository?
+
+No, but I'll teach you how to ignore `tags` globally:
+
+    git config --global core.excludesfile '~/.cvsignore'
+    echo tags >> ~/.cvsignore
+
+While any filename will work, I've chosen to follow the ancient
+tradition of `.cvsignore` because utilities like rsync use it, too.
+Clever, huh?
+
+> What about Vimballs?
+
+If you really must use one:
+
+    :e name.vba
+    :!mkdir ~/.vim/bundle/name
+    :UseVimball ~/.vim/bundle/name
+
+Contributing
+------------
+
+If your [commit message sucks](http://stopwritingramblingcommitmessages.com/),
+I'm not going to accept your pull request.  I've explained very politely
+dozens of times that
+[my general guidelines](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)
+are absolute rules on on my own repositories, so I may lack the energy
+to explain it to you yet another time.  And please, if I ask you to
+change something, `git commit --amend`.
+
+Beyond that, don't be shy about asking before patching.  What takes you
+hours might take me minutes simply because I have both domain knowledge
+and a perverse knowledge of Vim script so vast that many would consider
+it a symptom of mental illness.  On the flip side, some ideas I'll
+reject no matter how good the implementation is.  "Send a patch" is an
+edge case answer in my book.
