If PDF is electronic paper, then pdftk-java 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: 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, and repair corrupted PDF (where possible).

Pdftk-java is a port of the original GCJ-based PDFtk to Java. The GNU Compiler
for Java (GCJ) is a portable, optimizing, ahead-of-time compiler for the Java
programming language, which had no new developments since 2009 and was finally
removed in 2016 from the GCC development tree before the release of GCC 7.
