=head1 NAME

ansi2html - Convert ANSI sequence to HTML

=head1 SYNOPSIS

B<ansi2html> S<[ B<-p> B<-f> B<-c> ]> S<[ I<infile> ]> S<[ I<outfile> ]>

=head1 DESCRIPTION

This script takes one input file containing text with ANSI sequences,
and outputs the converted HTML code into another file.

If I<outfile> is omitted, it defaults to STDOUT.  If I<infile> is omitted,
it defaults to STDIN.

Note that this script will automatically set the C<fill_cols> option
to 1, filling empty columns with space characters.

If the B<-p> option is specified, it will print HTML header and footers.

If the B<-f> option is specified columns will not be filled.

If the B<-c> option is specified the cursor will be shown.
