The last example displays the faces and properties of all
perl hackers.

Please note that these shape properties are experimental and
may change in future A::E releases.

=head1 BUGS

A really diabolical shape with lots of single character lines
will defeat the shape-pouring algorithm.

You can eliminate all alphanumerics (via Regex => 1) only if the
program to be converted is careful with its use of regular
expressions and C<$_>.
To convert complex programs, you must use Regex => 0, which
emits a leading unsightly double C<eval>.

The code generated by non-zero Regex requires Perl 5.005 or higher
in order to run; when run on earlier versions, you will likely
see the error message: C<Sequence (?{...) not recognized>.

If using Perl 5.18+, the generated file needs a leading
"use re 'eval'" when a postive value for Regex is used.

The converted program runs inside an C<eval> which may cause
problems for non-trivial programs. A C<die> statement or
an C<INIT> block, for instance, may cause trouble.
If desperate, give the C<TrapEvalDie> and C<TrapWarn>
attributes a go, and see if they fix the problem.

If the program to be converted uses the Perl format variables
C<$:>, C<$~> or C<$^> you may need to explicitly set the
C<FillerVar> attribute to a Perl variable/s not used by the program.

Linux F</usr/games/banner> does not support the following characters:

    \ [ ] { } < > ^ _ | ~

When the CPAN Text::Banner module is enhanced, it will be used
in place of the Linux banner command.
