+modules.  @code{Log::Any::Adapter} allows applications to choose the mechanism
+for log consumption, whether screen, file or another logging mechanism like
+@code{Log::Dispatch} or @code{Log::Log4perl}.
+
+A CPAN module uses @code{Log::Any} to get a log producer object.  An
+application, in turn, may choose one or more logging mechanisms via
+@code{Log::Any::Adapter}, or none at all.
+
+@code{Log::Any} has a very tiny footprint and no dependencies beyond Perl
+itself, which makes it appropriate for even small CPAN modules to use.  It
+defaults to 'null' logging activity, so a module can safely log without
+worrying about whether the application has chosen (or will ever choose) a
+logging mechanism.")
