=head1 NAME
Perl::OSType - Map Perl operating system names to generic types
=head1 VERSION
version 1.002
=head1 SYNOPSIS
use Perl::OSType ':all';
$current_type = os_type();
$other_type = os_type('dragonfly'); # gives 'Unix'
=head1 DESCRIPTION
Modules that provide OS-specific behaviors often need to know if
the current operating system matches a more generic type of
operating systems. For example, 'linux' is a type of 'Unix' operating system
and so is 'freebsd'.
This module provides a mapping between an operating system name as given by
C<$^O> and a more generic type. The initial version is based on the OS type
mappings provided in L<Module::Build> and L<ExtUtils::CBuilder>. (Thus,
Microsoft operating systems are given the type 'Windows' rather than 'Win32'.)
=head1 USAGE
No functions are exported by default. The export tag ":all" will export
all functions listed below.
=head2 os_type()
$os_type = os_type();
$os_type = os_type('MSWin32');
Returns a single, generic OS type for a given operating system name. With no
arguments, returns the OS type for the current value of C<$^O>. If the
operating system is not recognized, the function will return the empty string.
=head2 is_os_type()
$is_windows = is_os_type('Windows');
$is_unix = is_os_type('Unix', 'dragonfly');
Given an OS type and OS name, returns true or false if the OS name is of the
given type. As with C<os_type>, it will use the current operating system as a
default if no OS name is provided.
