there's no renaming happening .. it's a print statement .. basically it's of
the form
print "some text";
see the double-quotes in the original statement .. they tell Perl to print
everything in between the quotes and perform variable interpolation on the
way .. so both $file and $newfile will have their values substituted for
them in the string
the single quotes are within the double quotes - so they're just part of the
print output
and the => is just a sequence of two characters that will also be printed
(although it means other things in other contexts)
this is all because there are double-quotes around everything .. so as far
as Perl is concerned - it's just a string to be printed
