#pod =head1 DESCRIPTION
#pod
#pod The Strict path packer is the simplest useful implementation of
#pod L.  It joins path parts together with a fixed string
#pod and splits them apart on the same string.  If the fixed string occurs any path
#pod part, an exception is thrown.

#pod
#pod The only valid argument is C, which is the string used to join path
#pod parts.  It defaults to a single period.
