How to upgrade PDF tools:
    PDF-Parser:
        Requires script to be renamed from pdf-parser.py to pdfparser.py
        cPDFDocument class needs to support StringIO:
            - self.infile = open(file, 'rb')
            + import io
            + self.infile = io.BytesIO(file)
    PDFid
        cBinaryFile class needs to support StringIO:
            - self.infile = open(file, 'rb')
            + import io
            + self.infile = io.BytesIO(file)
