+==================================

+
+
+NAME
+----
+cdist-type__package_pkgng_freebsd - Manage FreeBSD packages with pkg-ng
+
+
+DESCRIPTION
+-----------
+This type is usually used on FreeBSD to manage packages.
+
+
+REQUIRED PARAMETERS
+-------------------
+None
+
+
+OPTIONAL PARAMETERS
+-------------------
+name::
+    If supplied, use the name and not the object id as the package name.
+
+flavor::
+    If supplied, use to avoid ambiguity.
+
+version::
+    If supplied, use to install a specific version of the package named.
+
+repo::
+    If supplied, use to install the package named from a particular repo.
+
+state::
+    Either "present" or "absent", defaults to "present"
+
+
+BOOLEAN PARAMETERS
+------------------
+upgrade::
+    If supplied, allow upgrading to the latest version of a package.
+
+
+CAVEATS
+-------
+This type requires that repository definitions already exist in /etc/pkg/*.conf.
+Ensure that they exist prior to use of this type with __file.
+
+pkg-ng can't upgrade a package to a specific version. If this type needs to
+upgrade a package, it can only ugprade to the latest available version. If the
+"upgrade" parameter is not given and an upgrade needs to occur, an error will result.
+
+
+MESSAGES
+--------
+install::
+   The package was installed
+remove::
+   The package was removed
+upgrade::
+   The package was upgraded
+exist::
+   The package was already present and thus not installed
+
+
+EXAMPLES
+--------
+
+--------------------------------------------------------------------------------
+# Ensure zsh is installed
+__package_pkgng_freebsd zsh --state present
+
+# Ensure vim is installed, use flavor no_x11
+__package_pkgng_freebsd vim --state present --flavor no_x11
+
+# If you don't want to follow pythonX packages, but always use python
+__package_pkgng_freebsd python --state present --name python2
+
+# Install a package from a particular repository when multiples exist
+__package_pkgng_freebsd bash --state present --repo myrepo
+
+# Remove obsolete package
+__package_pkgng_freebsd puppet --state absent
