### Parse options

Usage: $program_name [OPTION]... FILE

$program_name builds a Debian package from the given Java binary distribution FILE

Supported java binary distributions currently include:
  * Oracle (http://www.oracle.com/technetwork/java/javase/downloads) :
    - The Java Development Kit (JDK), version 6, 7 and 8
    - The Java Runtime Environment (JRE), version 6, 7 and 8
    - The Java API Javadoc, version 6, 7 and 8
  (Choose tar.gz archives or self-extracting archives, do _not_ choose the RPM!)

The following options are recognized:

  --full-name NAME     full name used in the maintainer field of the package
  --email EMAIL        email address used in the maintainer field of the package
  --changes            create a .changes file
  --revision           add debian revision
  --source             build a source package instead of a binary deb package
  --with-system-certs  integrate with the system's keystore

  --help               display this help and exit
  --version            output version information and exit
