NAME

       AppConfig::Sys - Perl5 module defining platform-specific information and methods for other AppConfig::* modules.

SYNOPSIS

	   use AppConfig::Sys;
	   my $sys = AppConfig::Sys->new();

	   @fields = $sys->getpwuid($userid);
	   @fields = $sys->getpwnam($username);

OVERVIEW

       AppConfig::Sys is a Perl5 module provides platform-specific information and operations as required by other AppConfig::* modules.

       AppConfig::Sys is distributed as part of the AppConfig bundle.

DESCRIPTION

   USING THE AppConfig::Sys MODULE
       To import and use the AppConfig::Sys module the following line should appear in your Perl script:

	    use AppConfig::Sys;

       AppConfig::Sys is implemented using object-oriented methods.  A new AppConfig::Sys object is created and initialised using the
       AppConfig::Sys->new() method.  This returns a reference to a new AppConfig::Sys object.

	   my $sys = AppConfig::Sys->new();

       This will attempt to detect your operating system and create a reference to a new AppConfig::Sys object that is applicable to your
       platform.  You may explicitly specify an operating system name to override this automatic detection:

	   $unix_sys = AppConfig::Sys->new("Unix");

       Alternatively, the package variable $AppConfig::Sys::OS can be set to an operating system name.	The valid operating system names are:
       Win32, VMS, Mac, OS2 and Unix.  They are not case-specific.

   AppConfig::Sys METHODS
       AppConfig::Sys defines the following methods:

       getpwnam()
	   Calls the system function getpwnam() if available and returns the result.  Returns undef if not available.  The can_getpwnam() method
	   can be called to determine if this function is available.

       getpwuid()
	   Calls the system function getpwuid() if available and returns the result.  Returns undef if not available.  The can_getpwuid() method
	   can be called to determine if this function is available.
