 # This is a pure ruby library to combine/merge, stmap/overlay and number PDF files - as well as to create tables (ment for indexing combined files).
 #
 # You can also use this library for writing basic text content into new or existing PDF files (For authoring new PDF files look at the Prawn ruby library).
 #
 # here is the most basic application for the library, a one-liner that combines the PDF files and saves them:
