Libraries/Projects using [Composer](http://getcomposer.org) for dependency management should include a `.gitignore` file like this.

It ignores the vendor folder which Composer uses for dependencies, classmaps and others. Composer keeps git repositories in this folder so it is cleaner if it is ignored.

[`composer.lock` should not be ignored.](http://getcomposer.org/doc/01-basic-usage.md#composer-lock-the-lock-file)

> Commit your application's composer.lock (along with composer.json) into version control.

> For your library you may commit the composer.lock file if you want to. This can help your team to always test against the same dependency versions. However, this lock file will not have any effect on other projects that depend on it. It only has an effect on the main project.

Ignore Vim untitled and unsaved buffer swapfiles

This repository didn't have a CONTRIBUTING.md file. Now it does.

Per discussion in #148.

Unignore "packages/*/build" in VisualStudio.gitignore.

Vim creates buffer swapfiles starting at .swp for buffers that are
active but untitled and unsaved.

Updated to exclude *.publishsettings

Updated to exclude *.publishsettings

Erlang.gitignore erlang.crash.dump added

Add *~ to ignore vim temp file.

[Objective-C] No longer ignore `xcworkspace` documents.

VisualStudio: Add TeamCity exclusion

Changed line matching vim swapfiles to use all names it will create

More pr consolidation

Update VisualStudio.gitignore for vs 2012 web deploy setting.

Visual Studio 2010 Express for Windows Phone seems to generate .cachefile files.

If you use package restore, you actually don't want this file
included. It's not needed. It's only needed if you version
packages. AKA, you only need this file if you are not ignoring
the "packages" folder.

Dotnet gitignore pr consolidation

I agree to ignore the NuGet packages folder, but I really think you should check in the repositories.config so NuGet PackageRestore can do it's magic when someone pulls the code and tries to build it...

Add trailing slashes to folders, RS rule comment, remove dupes.

This might be created temporarily during a build.

VS2012 creates UpdateLog2.htm - not needed in git repository

New web deploy file name? vs 2012 added this to my solution and it shouldn't go to an open repo.

Consolidate CSharp and VB.NET gitignore files into VisualStudio one.

Cross platform .NET Dev FTW!

Changed line matching vim swapfiles to use all names it will create as described in http://vimdoc.sourceforge.net/htmldoc/recover.html#E326

Added __pycache__

Rename Wordpress.gitignore to WordPress.gitignore

WordPress should *always* have a capital P!

Workspaces are real documents that can be opened, just like `xcodeproj`
documents. These documents are also generated/used by CocoaPods to
configure a project’s dependencies. For these reasons, there does not
seem a good reason to ignore these any longer.
