NAME
    File::cd - Easily and safely change directory

VERSION
    version 0.002

SYNOPSIS
      use 5.010;
      use File::cd;
      use Cwd qw(cwd);

      cd '/tmp' => sub {
          # output: /tmp
          say cwd;

          # do something in /tmp
          process_directory();

          # we can also nest multiple cds
          cd '/home/foo' => sub { ... };
      };

      # back at original directory
      say cwd;

DESCRIPTION
    The global (and negative) effect of perl builtin function "chdir" is
    well known (see File::chdir's documentation for more details). And few
    modules have been created to solve this problem:

    *   File::chdir, by David Golden.

    *   File::pushd, also by David Golden.

    *   Cwd::Guard, by Masahiro Nagano.

    Unfortunately, I'm not a big fan of their interface. So this modules
    provides yet another way to change directory in perl.

  FUNCTIONS
    Exports the function "cd" by default.

  cd($dir, $code)
    Change directory to $dir, invoke the function reference $code inside
    that directory, and go back to original directory.

    The return value of this function is the value of the last expression in
    $code. Here's an example to utilize it:

      # get a list of files contained in directory /home/example
      use File::Spec qw(catfile);

      my $destination = '/home/example';

      my @files = cd $destination => sub {
          map { catfile $destination, $_ } glob '*'
      }

      # make sure to match the context!
      my $files = cd $destination => sub {
          [ map { catfile $destination, $_ } glob '*' ]
      }

    Throws an exception when the directory $dir does not exist or is not a
    directory.

    NOTE: This function is prototyped, which means the validity of supplied
    arguments are checked at compile time.
