=head1 NAME
Text::AsciiTeX - Convert (La)TeX formulas to ASCII art
=head1 SYNOPSIS
use Text::AsciiArt;
#equivalent examples
my @text_array = render('\frac{1}{e}');
print "$_\n" for @text_array;
my $text_array = render('\frac{1}{e}');
print $text_array;
print scalar render('\frac{1}{e}');
render('\frac{1}{e}');
=head1 DESCRIPTION
This module provides a mechanism to render (La)TeX formulae to ASCII art. It is based solely on F<AsciiTeX> written by Bart Pieters (See L</"UNDERLYING TECHNOLOGIES">).
=head1 EXPORTED FUNCTION
This module exports the C<render> function.
=head2 C<< render( $latex [, $columns] ) >>
=head3 Argument(s)
The function C<render> accepts a string containing a formula in (La)TeX formatting. Optionally, an integer may be given to specify the number of columns for the output or zero for no-breaking. The default number of columns is 80.
=head3 Return
Since version 0.03 the return value is context aware.
=over
=item *
In list context, C<render> returns a list whose elements are strings, one for each row of the art. Printing each line, terminated by a newline will probably do what you expect.
=item *
In scalar context, C<render> will return a string of the concatenated lines, each ended with a newline.
=item *
In void context, C<render> will print the scalar context return directly to the C<select>ed file handle (usually C<STDOUT>).
=back
=head1 EXAMPLES
For use examples see L</SYNOPSIS>. For a list of allowed syntax and syntax examples read L<Text::AsciiTeX::Syntax>.
=head1 UNDERLYING TECHNOLOGIES
This module is basically just a C-level Perl wrapper of F<AsciiTeX> written by Bart Pieters. That project is hosted at L<http://asciitex.sourceforge.net/>. F<AsciiTeX> in turn was a fork of F<eqascii> which was written by Przemek Borys. This module owes a debt of thanks to both authors.
