=head1 NAME

Filter::exec - exec source filter

=head1 SYNOPSIS

use Filter::exec qw(command parameters) ;

=head1 DESCRIPTION

This filter pipes the current source file through the program which
corresponds to the C<command> parameter.

As with all source filters its scope is limited to the current source
file only. Every file you want to be processed by the filter must have a

use Filter::exec qw(command ) ;

near the top.

Here is an example script which uses the filter:

use Filter::exec qw(tr XYZ PQR) ;
    $a = 1 ;
    print "XYZ a = $a\n" ;

And here is what it will output:

PQR = 1

=head1 WARNING

You should be I<very> careful when using this filter. Because of the
way the filter is implemented it is possible to end up with deadlock.

Be especially careful when stacking multiple instances of the filter in
a single source file.
