SYNOPSIS

	 use Mojo::Asset::File;

	 # Temporary file
	 my $file = Mojo::Asset::File->new;
	 $file->add_chunk('foo bar baz');
	 say 'File contains "bar"' if $file->contains('bar') >= 0;
	 say $file->slurp;

	 # Existing file
	 my $file = Mojo::Asset::File->new(path => '/home/sri/foo.txt');
	 $file->move_to('/yada.txt');
	 say $file->slurp;

DESCRIPTION

       Mojo::Asset::File is a file storage backend for HTTP 1.1 content.

ATTRIBUTES

       Mojo::Asset::File inherits all attributes from Mojo::Asset and implements the following new ones.

   "cleanup"
	 my $cleanup = $file->cleanup;
	 $file	     = $file->cleanup(1);

       Delete file automatically once it's not used anymore.

   "handle"
	 my $handle = $file->handle;

       File handle, created on demand.

   "path"
	 my $path = $file->path;
	 $file	  = $file->path('/home/sri/foo.txt');

       File path used to create "handle", can also be automatically generated if necessary.

   "tmpdir"
	 my $tmpdir = $file->tmpdir;
	 $file	    = $file->tmpdir('/tmp');

       Temporary directory used to generate "path", defaults to the value of the "MOJO_TMPDIR" environment variable or auto detection.

   "move_to"
