=head1 NAME

ctflags::long - use ctflags with long names

=head1 SYNOPSIS

  use ctflags::long;


=head1 ABSTRACT

Reference ctflags with long names instead of using single letters.

=head1 DESCRIPTION

After C<ctflags::config> has been used to assign long names to
ctflags, this package can be used to import the flags as normal Perl
constants but refering to the flags by its long name. i.e.:

  use ctflags::config long => 'foo:bar=b';
  use ctflags::long 'my_bar=foo:bar';

the first line creates an alias for foo:b as foo:bar, the second line
imports foo:bar (and so, foo:b) as constant my_bar.

=head2 EXPORT

The requested flags
