=head1 DIAGNOSTICS

I<Warning:> Couldn't remove lockfile $lock: $!


I<Error:> Failed to remove expired lockfile $lockfile: $!


I<Warning:> Folder already locked with file $lockfile


I<Error:> Package $package does not implement $method.

Fatal error: the specific package (or one of its superclasses) does not
implement this method where it should. This message means that some other
related classes do implement this method however the class at hand does
not.  Probably you should investigate this and probably inform the author
of the package.
