=head1 NAME

Path::Resolver::Resolver::FileSystem - find files in the filesystem

=head1 VERSION

version 3.100455

=head1 SYNOPSIS

  my $resolver = Path::Resolver::Resolver::FileSystem->new({
    root => '/etc/myapp_config',
  });

  my $simple_entity = $resolver->entity_at('foo/bar.txt');

This resolver looks for files on disk under the given root directory.

This resolver does the
L<Path::Resolver::Role::FileResolver|Path::Resolver::Role::FileResolver> role,
meaning its native type is Path::Resolver::Types::AbsFilePath and it has a
default converter to convert to Path::Resolver::SimpleEntity.

=head1 PERL VERSION

This library should run on perls released even a long time ago.  It should work
on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.

=head1 ATTRIBUTES

=head2 root

This is the root on the filesystem under which to look.  If it is relative, it
will be resolved to an absolute path when the resolver is instantiated.
