+=head1 NAME
+
+TAP::Parser::Source::Perl - Stream Perl output
+
+=head1 VERSION
+
+Version 3.12
+
+=cut
+
+$VERSION = '3.12';
+
+=head1 SYNOPSIS
+
+  use TAP::Parser::Source::Perl;
+  my $perl = TAP::Parser::Source::Perl->new({ parser => $parser });
+  my $stream = $perl->source( [ $filename, @args ] )->get_stream;
+
+=head1 DESCRIPTION
+
+Takes a filename and hopefully returns a stream from it.  The filename should
+be the name of a Perl program.
+
+Note that this is a subclass of L<TAP::Parser::Source>.  See that module for
+more methods.
+
+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<new>
+
+ my $perl = TAP::Parser::Source::Perl->new({ parser => $parser });
+
+Returns a new C<TAP::Parser::Source::Perl> object.
+
+=head2 Instance Methods
+
+=head3 C<source>
+
+Getter/setter the name of the test program and any arguments it requires.
+
+  my ($filename, @args) = @{ $perl->source };
+  $perl->source( [ $filename, @args ] );
+
+C<croak>s if C<$filename> could not be found.

+}
+
+=head3 C<switches>
+
+  my $switches = $perl->switches;
+  my @switches = $perl->switches;
+  $perl->switches( \@switches );
+
+Getter/setter for the additional switches to pass to the perl executable.  One
+common switch would be to set an include directory:
+
+  $perl->switches( ['-Ilib'] );
+
