This plugin enables access to YaST via an openwsman plugin.

Its namespace is
  http://schema.opensuse.org/YaST/wsman-schema/10-3

The inital release only implements the 'Custom' endpoint,
serving the 'invoke' ws-man command.

A single resource class 'YCP' is implemented with
one method
  eval (ycp : string) -> string

It evaluates a piece of ycp code in the client environment.


The ycp code follows the same rules as other yast programs:
 - must be enclosed in {  }
 - required modules must be 'import'ed
 - the result of the eval method is the value returned by
   the first 'return' statement encountered.

Examples of valid ycp code:

1. Simple computation

  { integer i = 42; float j = 10.3; return i+j; }


2. Read /proc/modules

  { return SCR::Read( .proc.modules ); }


3. Call a method from the 'String' module (returns "4.00 KB")

  { import "String"; return String::FormatSizeWithPrecision( 4096, 2, false ); }


4. Get partitioning information

  { import "Storage"; return Storage::GetDiskPartition("/dev/sda1"); }
