perl-YAML-Tiny (Read/Write YAML files with a little code as possible)

The YAML specification is huge.  Really, really huge. It contains all
the functionality of XML,  except  with flexibility and choice, which
makes it easier to read, but with a formal specification that is more
complex than XML.

The original pure-Perl implementation YAML costs just over 4 megabytes
of memory to load.  Just like with  Windows .ini files (3 meg to load)
and  CSS  (3.5 meg to load)  the  situation  is  just  asking  for  a
YAML::Tiny module, an incomplete but correct and usable subset of the
functionality, in as little code as possible.
