+cdist-type__sensible_editor(7)
+==============================
+
+NAME
+----
+cdist-type__sensible_editor - Select the sensible-editor
+
+
+DESCRIPTION
+-----------
+This cdist type allows you to select the :strong:`sensible-editor` for
+a given user.
+
+
+REQUIRED PARAMETERS
+-------------------
+editor
+    Name or path of the editor to be selected.
+    On systems other than Debian derivatives an absolute path is required.
+
+	It is permissible to omit this parameter if --state is absent.
+
+
+OPTIONAL PARAMETERS
+-------------------
+state
+    'present', 'absent', or 'exists'. Defaults to 'present', where:
+
+    present
+        the sensible-editor is exactly what is specified in --editor.
+    absent
+        no sensible-editor configuration is present.
+    exists
+        the sensible-editor will be set to what is specified in --editor,
+        unless there already is a configuration on the target system.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    __sensible_editor root --editor /bin/ed  # ed(1) is the standard
+    __sensible_editor noob --editor nano
+
+
+LIMITATIONS
+-----------
+
+This type depends upon the :strong:`sensible-editor`\ (1) script which
+is part of the sensible-utils package.
+
+Therefore, the following operating systems are supported:
+  * Debian 8 (jessie) or later
+  * Devuan
+  * Ubuntu 8.10 (intrepid) or later
+  * RHEL/CentOS 7 or later (EPEL repo required)
+  * Fedora 21 or later
+
+Note: on old versions of Ubuntu the sensible-* utils are part of the
+debianutils package.
+
+SEE ALSO
+--------
+:strong:`select-editor`\ (1), :strong:`sensible-editor`\ (1).

+NAME
+----
+cdist-type__xymon_apache - Configure apache2-webserver for Xymon
+
+
+DESCRIPTION
+-----------
+This cdist type installs and configures apache2 to be used "exclusively" (in
+the sense that no other use is taken care of) with Xymon (the systems and
+network monitor).
+
+It depends on `__xymon_server`.
+
+
+REQUIRED PARAMETERS
+-------------------
+None.
+
+
+OPTIONAL PARAMETERS
+-------------------
+state
+   'present', 'absent', defaults to 'present'.
+
+ipacl
+   IP(-ranges) that have access to the Xymon webpages and CGIs. Apache2-style
+   syntax suitable for `Require ip ...`. Example: `192.168.1.0/24 10.0.0.0/8`
+
+
+MESSAGES
+--------
+mod:rewrite enabled
+   apache module enabled
+conf:xymon enabled
+   apache config for xymon enabled
+apache restarted
+   apache2.service was reloaded
+apache reloaded
+   apache2.service was restarted
+
+
+EXPLORERS
+---------
+active-conf
+   lists apache2 `conf-enabled`
+active-modules
+   lists active apache2-modules
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # minmal, only localhost-access:
+    __xymon_apache
+    # allow more IPs to access the Xymon-webinterface:
+    __xymon_apache --ipacl "192.168.0.0/16 10.0.0.0/8" --state "present"

+===========================
+
+NAME
+----
+cdist-type__xymon_config - Deploy a Xymon configuration-directory
+
+
+DESCRIPTION
+-----------
+This cdist type deploys a full Xymon configuration directory from the files-dir
+to the host.  This type requires an installed Xymon server, e.g. deployed by
+`__xymon_server`.
+
+WARNING: This type _replaces_ the `/etc/xymon/`-directory! The previous
+contents is replaced/deleted!
+
+
+REQUIRED PARAMETERS
+-------------------
+confdir
+   The directory in `./files/` that contains the `/etc/xymon/`-content to be
+   deployed.
+
+
+REQUIRED FILES
+--------------
+The directory specified by `confdir` has to contain a valid xymon-configuration
+(`/etc/xymon/`) _plus_ the `ext/`-directory that normally resides in
+`/usr/lib/xymon/server/`.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    __xymon_config --confdir=xymon.example.com
+    # this will replace /etc/xymon/ on the target host with
+    # the contents from __xymon_config/files/xymon.example.com/

+===========================
+
+NAME
+----
+cdist-type__xymon_server - Install a Xymon server
+
+
+DESCRIPTION
+-----------
+This cdist type installs a Xymon (https://www.xymon.com/) server and (optional)
+required helper packages.
+
+This includes the Xymon client as a dependency, so NO NEED to install
+`__xymon_client` separately.
+
+To access the webinterface a webserver is required.  The cdist-type
+`__xymon_apache` can be used to install and configure the apache webserver for
+the use with Xymon.
+
+Further and day-to-day configuration of Xymon can either be done manually in
+`/etc/xymon/` or the directory can be deployed and managed by `__xymon_config`.
+
+
+REQUIRED PARAMETERS
+-------------------
+None.
+
+
+OPTIONAL PARAMETERS
+-------------------
+state
+    'present', 'absent', defaults to 'present'. If '--install_helpers' is
+    specified for 'absent' the helper packages will be un-installed.
+
+
+BOOLEAN PARAMETERS
+------------------
+install_helpers
+    Install helper packages used by Xymon (fping, heirloom-mailx, traceroute,
+    ntpdate).
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # minmal
+    __xymon_server
+
+    # the same
+    __xymon_server --state present
+
+    # also install helper packages:
+    __xymon_server --install_helpers
+
+    # examples to give a more complete picture: __xymon_server installed on
+    # `xymon.example.com` w/ IP 192.168.1.1:
+    #
+    # install webserver and grant 2 private subnets access to the webinterface:
+    __xymon_apache --ipacl "192.168.0.0/16 10.0.0.0/8"
+    # deploy server-configuration with __xymon_config:
+    __xymon_config --confdir=xymon.example.com
+
+    # install xymon-client on other machines (not needed on the server):
+    __xymon_client --servers "192.168.1.1"
