Perl module mapping operating system names to generic types

 Modules that provide OS-specific behaviors often need to know if the current
 operating system matches a more generic type of operating systems. For
 example, 'linux' is a type of 'Unix' operating system and so is 'freebsd'.
 .
 Perl::OSType provides a mapping between an operating system name as given by
 $^O and a more generic type. The initial version is based on the OS type
 mappings provided in Module::Build and ExtUtils::CBuilder. (Thus, Microsoft
 operating systems are given the type 'Windows' rather than 'Win32'.)
