Location:http://e-p-i-c.sourceforge.net/updates/testing
2, 安装Padwalker：
PadWalker is a module which allows you to inspect (and even change!)
lexical variables in any subroutine which called you. It will only show
those variables which are in scope at the point of the call.
PadWalker is particularly useful for debugging. It’s even used by
Perl’s built-in debugger. (It can also be used for evil, of course.)
11.download it from CPAN(http://search.cpan.org/dist/PadWalker/).
22. unzip and extract it to \lib
33. exec perl Makefile.pl
44. make;nmake test;make install
