If PDF is electronic paper, then pdftk is an electronic staple-remover,
hole-punch, binder, secret-decoder-ring, and X-Ray-glasses. Pdftk is a
simple tool for doing everyday things with PDF documents. Keep one in
the top drawer of your desktop and use it to:

    * Merge PDF Documents * Split PDF Pages into a New Document * Decrypt
    Input as Necessary (Password Required) * Encrypt Output as Desired
    * Burst a PDF Document into Single Pages * Report on PDF Metrics,
    including Metadata and Bookmarks * Uncompress and Re-Compress Page
    Streams * Repair Corrupted PDF (Where Possible)

Pdftk is also an example of how to use a library of Java classes in a
stand-alone C++ program. Specifically, it demonstrates how GCJ and CNI
allow C++ code to use iText's (itext-paulo) Java classes.
