You are looking at a documentation format known as Pod: Plain Old
Documentation. The markup is simple. The C<...> tag means "this is to be
rendered as code".
Try using pod2html or pod2text to see the Pod rendered in a different
format. Also, look at the 'perlpod' documentation for information on
writing Pod.

The /m modifier (documented in perlre) changes the meaning of the ^ and $
anchors. You can read more about this in chapter 3 of "Learning Perl's
Regular Expressions", which you can find online at
http://www.pobox.com/~japhy/docs/LPRE.html
>=item Comments Inside the Regexp
This, too, is Pod markup. The =item directive (found inside =over and
=back directives) is used to indicate a list element.

The perldoc tool comes with Perl, and is very simple to use. In fact, you
can find out how by running 'perldoc perldoc' at your command-line. ;)
Very briefly:
perldoc SECTION
read a specific file of documentation (like perlfunc or perlmod)
perldoc -f FUNCTION
extract information about FUNCTION from perlfunc.pod
perldoc -q KEYWORD
search the FAQ for a question containing KEYWORD
You can also access this information online at http://www.perldoc.org/.

Most people leave out the "return" because it is redundant. But any true
value will do:
1;
"this is not true";
"japhy told me to put this here";
