If there are two modules using C<FindBin> from different directories

+under the same interpreter, this won't work. Since C<FindBin> uses a
C<BEGIN> block, it'll be executed only once, and only the first caller
will get it right. This is a problem under mod_perl and other persistent
Perl environments, where you shouldn't use this module. Which also means
that you should avoid using C<FindBin> in modules that you plan to put
-on CPAN. The only way to make sure that C<FindBin> will work is to force

+In former versions of FindBin there was no C<again> function. The
+workaround was to force the C<BEGIN> block to be executed again:
delete $INC{'FindBin.pm'};
