Pdftk is a Ruby wrapper around the unix CLI tool pdftk
pdftk makes a number of different options easy to perform, except it's a pain to use it to:
- query a PDF's fillable form fields
- export a new PDF with filled out form fields
This gem is mainly geared towards querying and filling out PDF form fields but, because it wraps pdftk, we may wrap all of the available pdftk commands.
