+=head1 KNOWN ISSUES
+
+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. To make sure that C<FindBin> will work is to call the C<again>
+function:
+
+ use FindBin;
+ FindBin::again(); # or FindBin->again;
+
+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'};
+ require FindBin;
