=head1 NAME
Carton::Doc::Install - Install the dependencies
=head1 SYNOPSIS
carton install [--deployment] [--path=PATH]
=head1 DESCRIPTION
Install the dependencies for your application. This command has two
modes and the behavior is slightly different.
=head2 DEVELOPMENT MODE
=over 4
=item carton install
If you run C<carton install> without any arguments and if I<cpanfile>
exists, carton will scan dependencies from I<cpanfile> and install
the modules.
=back
In either way, if you run C<carton install> for the first time
(i.e. I<carton.lock> does not exist), carton will fetch all the
modules specified, resolve dependencies and install all required
modules from CPAN.
If I<carton.lock> file does exist, carton will still try to install
modules specified or updated in I<cpanfile>, but uses I<carton.lock>
for the dependency resolution, and then cascades to CPAN.
carton will analyze all the dependencies and their version
information, and it is saved into I<carton.lock> file. It is important
to add I<carton.lock> file into a version controlled repository and
commit the changes as you update your dependencies.
=head2 DEPLOYMENT MODE
If you specify the C<--deployment> command line option or the
I<carton.lock> exists, carton will fetch all remote modules and use
the dependencies specified in the I<carton.lock> instead of resolving
dependencies.
=head1 OPTIONS
=over 4
=item --deployment
Force the deployment mode and carton will ignore I<cpanfile> contents.
=item --path
Specify the path to install modules to. Defaults to I<local> in the current directory.
