       Much like the C preprocessor, Perl can process line
       directives.  Using this, one can control Perl's idea of
       filenames and line numbers in error or warning messages
       (especially for strings that are processed with eval()).
       The syntax for this mechanism is the same as for most C
       preprocessors: it matches the regular expression
       /^#\s*line\s+(\d+)\s*(?:\s"([^"]*)")?/ with $1 being the
       line number for the next line, and $2 being the optional
       filename (specified within quotes).

       Here are some examples that you should be able to type
       into your command shell:

and goes on to give some examples.
