Libraries

Libraries are the major upgdrade to MBuild 0.5
You can store objects, brushes, tags, etc..
into a library file and use it for multiple levels.
This eliminates the need for having to alot of repetitios
work in making levels.
The LIB.MPB file included is made up of some sample 
library files(.MBL) that are in the \lib directory.
You can call library files by using the following command:

file <mylib.mbl> x y z

'mylib.mbl' specifies the file to use and 'x y z' specifies
the origin that will be used when placing the contents of the file.

NOTE: You CANNOT embed libraries inside of libraries.
      This means that you cannot call another librarie
      from within one.
