pdfextract a cool ruby tool that uses pdf-reader

[Dominic Sisneros]

I was looking for ruby pdf tools and came across this on github

https://github.com/CrossRef/pdfextract.git

It uses pdf-reader to analyzethe spatial information of text as well as heuristics to
extract --regions or --columns --headers etc from a pdf file. 


Another cool ruby pdf library is origami which uses its own library to parse pdf-files. This one allows you to modify the pdf file
