.SH DESCRIPTION
.IX Header "DESCRIPTION"
This is an \fIexecutable\fR TAP::Parser::SourceHandler \- it has 2 jobs:
.PP
1. Figure out if the TAP::Parser::Source it's given is an executable
   command ("can_handle").
.PP
2. Creates an iterator for executable commands ("make_iterator").
.PP
Unless you're writing a plugin or subclassing TAP::Parser, you
probably won't need to use this module directly.
