NAME
   Carton - Perl module dependency manager (aka Bundler for Perl)

SYNOPSIS
     # On your development environment
     > cat cpanfile
     requires 'Plack', 0.9980;
     requires 'Starman', 0.2000;

     > carton install
     > git add cpanfile carton.lock
     > git commit -m "add Plack and Starman"

     # Other developer's machine, or on a deployment box
     > carton install
     > carton exec -Ilib -- starman -p 8080 myapp.psgi

WARNING
   This software is under heavy development and considered ALPHA quality
   till its version hits v1.0.0. Things might be broken, not all features
   have been implemented, and APIs are likely to change. YOU HAVE BEEN
   WARNED.

DESCRIPTION
   carton is a command line tool to track the Perl module dependencies for
   your Perl application. The managed dependencies are tracked in a
   *carton.lock* file, which is meant to be version controlled, and the
   lock file allows other developers of your application will have the
   exact same versions of the modules.

TUTORIAL
 Initializing the environment
   carton will use the *.carton* directory for local configuration and the
   *local* directory to install modules into. You're recommended to exclude
   these directories from the version control system.

     > echo .carton/ >> .gitignore
     > echo local/ >> .gitignore
     > git add carton.lock
     > git commit -m "Start using carton"

 Tracking the dependencies
   You can manage the dependencies of your application via *cpanfile*.

     # cpanfile
     requires 'Plack', 0.9980;
     requires 'Starman', 0.2000;

   And then you can install these dependencies via:

     > carton install

   The modules are installed into your *local* directory, and the
   dependencies tree and version information are analyzed and saved into
   *carton.lock* in your directory.

   Make sure you add *carton.lock* to your version controlled repository
   and commit changes as you update dependencies. This will ensure that
   other developers on your app, as well as your deployment environment,
   use exactly the same versions of the modules you just installed.

     > git add cpanfile carton.lock
     > git commit -m "Added Plack and Starman"

 Deploying your application
   Once you've done installing all the dependencies, you can push your
   application directory to a remote machine (excluding *local* and
   *.carton*) and run the following command:

     > carton install

   This will look at the *carton.lock* and install the exact same versions
   of the dependencies into *local*, and now your application is ready to
   run.

 Bundling modules
   carton can bundle all the tarballs for your dependencies into a
   directory so that you can even install dependencies that are not
   available on CPAN, such as internal distribution aka DarkPAN.

     > carton bundle

   will bundle these tarballs into *local/cache* directory, and

     > carton install --cached

   will install modules using this local cache. This way you can avoid a
   dependency on CPAN meta DB and search.cpan.org at a deploy time, or you
   can have dependencies onto private CPAN modules aka DarkPAN.
