Overview

Given a Batch object that has many associated letters, it

  • compiles each letter with a cover sheet for each recipient, adding blank padding pages if needed to ensure the envelop stuffer will work correctly (ie each letter starts on an odd page)

  • combines all these letter PDFs into one batch PDF. The output filepath is stored on the

batch model.

Note that this class creates files and combines them using ghost script. These operations take place in the current working directory, so to use this class you might need to create a OS tmp folder first and cdhir into it. See the spec for an example.
