=head1 DESCRIPTION

This module searches the first non-empty environment variable with one of the
names given at import time, parses it like the Unix shell (using
L<Text::ParseWords>::shellwords) and insert the result at the beginning of
C<@ARGV>.

This module is helpful to implement command-line scripts that take some
global config as an environnement variable containing command-line flags.

This module is named C<ARGV::ENV> (and not C<Argv::Env> or C<@ARGV::Env>)
because the perl built-in global variables C<@ARGV> and C<@ENV> are both in
upper case.
