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
command-line 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 documents, apply watermarks, repair corrupt PDF, update PDF
metadata, and more. pdftk does not require Acrobat and is free software.
NOTE: Starting with Slackware 15.0 pdftk compilation requires SBo gcc-5
because gcc-java was dropped from the GNU Compiler Collection as of gcc-7:
don't forget to source /etc/profile.d/gcc5.sh before starting to build
this, like
. /etc/profile.d/gcc5.sh
