     # Tie Interface
     use Env::ShellWords;
     tie my @CFLAGS,  'Env::ShellWords', 'CFLAGS';
     tie my @LDFLAGS, 'Env::ShellWords', 'LDFLAGS';
    
     # same thing with import interface:
     use Env::ShellWords qw( @CFLAGS @LDFLAGS );
    
     # usage:
     $ENV{CFLAGS} = '-DBAR=1';
     unshift @CFLAGS, '-I/foo/include';
     push @CFLAGS, '-DFOO=Define With Spaces';
     
     # now:
     # $ENV{CFLAGS} = '-I/foo/include -DBAR=1 -DFOO=Define\\ With\\ Spaces';

DESCRIPTION

    This module provides an array like interface to environment variables
    that contain flags. For example Autoconf can uses the environment
    variables like CFLAGS or LDFLAGS, and this allows you to manipulate
    those variables without doing space quoting and other messy mucky
