.SH "DESCRIPTION"
.IX Header "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 TAP::Parser::Source.  See that module for
more methods.

Getter/setter for the additional switches to pass to the perl executable.  One
common switch would be to set an include directory:

.PP
Returns a stream of the output generated by executing \f(CW\*(C`source\*(C'\fR. Must be
passed an object that implements a \f(CW\*(C`make_iterator\*(C'\fR method. Typically
this is a TAP::Parser instance.
.PP
\fI\f(CI\*(C`shebang\*(C'\fI\fR
