More sensible way to change directories
Perl’s chdir has the unfortunate problem of being very, very, very global. If any part of your program calls chdir or if any library you use calls chdir, it changes the current working directory for the whole program.
Filechdir gives you an alternative, $CWD and @CWD. These two variables combine all the power of chdir, FileSpec and Cwd.
