=head1 NAME

Siebel::AssertOS - verifies if the OS is supported by Siebel applications


    package Your::Package;
	use Siebel::AssertOS;


This modules will help identifying if the current OS that is running is supported by Siebel applications. If not, the module will C<die>, 
forcing the code to stop being executed.

This is particulary useful for automated tests.

The list of supported OS is as defined by Oracle documentation regarding Siebel 8.2 and the list of OS from L<Devel::CheckOS> distribution. Actually, 
Siebel::AssertOS is based on L<Devel::CheckOS>, borrowing code from it, but does not depend on it.

Regarding supported Linux distributions, this module will also validate if the code is running on a supported by Siebel distribution.

=head2 EXPORT

None, but the functions below can be used by calling them with the complete package name (C<Siebel::AssertOS::FUNCTION>).

=head3 die_if_os_isnt

Expects an optional string parameter with the operational system name. If not given, it will assume C<$^O> as default.

It will execute C<os_is> with the operational system name, calling C<die_unsuported> if the return value from C<os_is> is false.

Beware that the given parameter must follow the same provided by C<$^O>, including case and format.
C<die_if_os_isnt> is called by default when the module is imported to another package.

=head3 die_unsupported

Expects a string as parameter.

Will execute C<die> with a message telling that the parameter is not supported.

=head3 os_is

Expects a string as parameter, being the string the OS name.

Returns true or false depending on the give value. The string is restricted by those return by C<$^O> special variable.
