#pod =head1 OVERVIEW
#pod
#pod This summarizer will summarize simple, non-empty strings by accepting them
#pod verbatim.  They are assumed to be text, and will be encoded to UTF-8.  If that
#pod fails, they will be used verbatim, possibly with strange results.
#pod
#pod The summary's C will be the first non-blank line of the string.
