module: pkgutil 
short_description: Manage CSW-Packages on Solaris
description:
    - Manages CSW packages (SVR4 format) on Solaris 10 and 11.
    - These were the native packages on Solaris <= 10 and are available
      as a legacy feature in Solaris 11.
    - Pkgutil is an advanced packaging system, which resolves dependency on installation.
      It is designed for CSW packages.
version_added: "1.3"
author: Alexander Winkler
options:
  name:
    description:
      - Package name, e.g. (C(CSWnrpe))
    required: true
  site:
    description:
      - Specifies the repository path to install the package from.
      - Its global definition is done in C(/etc/opt/csw/pkgutil.conf).
  state:
    description:
      - Whether to install (C(present)), or remove (C(absent)) a package.
      - The upgrade (C(latest)) operation will update/install the package to the latest version available.
      - "Note: The module has a limitation that (C(latest)) only works for one package, not lists of them."
    required: true
    choices: ["present", "absent", "latest"]

EXAMPLES = '''
# Install a package
