Package pdftk: Information

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.
