use YAPE::Regex::Explain;
print YAPE::Regex::Explain->new ('[^/]*$')->explain ();

The regular expression:

( ?-imsx:[^/]*$ )

matches as follows:

NODE EXPLANATION
----------------------------------------------------------------------
(?-imsx: group, but do not capture (case-sensitive)
(with ^ and $ matching normally) (with . not
matching \n) (matching whitespace and #
normally):
----------------------------------------------------------------------
[^/]* any character except: '/' (0 or more times
(matching the most amount possible))
----------------------------------------------------------------------
$ before an optional \n, and the end of the
string
----------------------------------------------------------------------
) end of grouping
----------------------------------------------------------------------
