+cdist-type__apt_pin(7)
+======================
+
+NAME
+----
+cdist-type__apt_pin - Manage apt pinning rules
+
+
+DESCRIPTION
+-----------
+Adds/removes/edits rules to pin some packages to a specific distribution. Useful if using multiple debian repositories at the same time. (Useful, if one wants to use a few specific packages from backports or perhaps Debain testing... or even sid.)
+
+
+REQUIRED PARAMETERS
+-------------------
+distribution
+   Specifies what distribution the package should be pinned to. Accepts both codenames (buster/bullseye/sid) and suite names (stable/testing/...).
+
+
+OPTIONAL PARAMETERS
+-------------------
+package
+   Package name, glob or regular expression to match (multiple) packages. If not specified `__object_id` is used.
+
+priority
+   The priority value to assign to matching packages. Deafults to 500. (To match the default target distro's priority)
+
+state
+   Will be passed to underlying `__file` type; see there for valid values and defaults.
+
+
+
+BOOLEAN PARAMETERS
+------------------
+None.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+   # Add the bullseye repo to buster, but do not install any packages by default,
+   # only if explicitely asked for (-1 means "never" for apt)
+    __apt_pin bullseye-default \
+       --package "*" \
+       --distribution bullseye \
+       --priority -1
+
+    require="__apt_pin/bullseye-default" __apt_source bullseye \
+       --uri http://deb.debian.org/debian/ \
+       --distribution bullseye \
+       --component main
+
+    __apt_pin foo --package "foo foo-*" --distribution bullseye
+
+    __foo # Assuming, this installs the `foo` package internally
+
+    __package foo-plugin-extras # Assuming we also need some extra stuff

 NAME
 ----
-cdist-type__rsync - Mirror directories using rsync
+cdist-type__rsync - Mirror directories using ``rsync``
 
 
 DESCRIPTION
 -----------
-WARNING: This type is of BETA quality:
-
-- it has not been tested widely
-- interfaces *may* change
-- if there is a better approach to solve the problem -> the type may even vanish
-
-If you are fine with these constraints, please read on.
-
-
-This cdist type allows you to mirror local directories to the
-target host using rsync. Rsync will be installed in the manifest of the type.
-If group or owner are giveng, a recursive chown will be executed on the 
-target host.
-
-A slash will be appended to the source directory so that only the contents
-of the directory are taken and not the directory name itself.
+The purpose of this type is to bring power of ``rsync`` into ``cdist``.
 
 
 REQUIRED PARAMETERS
 -------------------
 source
-    Where to take files from
+   Source directory in local machine.
+   If source is directory, slash (``/``) will be added to source and destination paths.
 
 
 OPTIONAL PARAMETERS
 -------------------
-group
-   Group to chgrp to.
+destination
+   Destination directory. Defaults to ``$__object_id``.
 
 owner
-   User to chown to.
+   Will be passed to ``rsync`` as ``--chown=OWNER``.
+   Read ``rsync(1)`` for more details.
 
-destination
-    Use this as the base destination instead of the object id
+group
+   Will be passed to ``rsync`` as ``--chown=:GROUP``.
+   Read ``rsync(1)`` for more details.
+
+mode
+   Will be passed to ``rsync`` as ``--chmod=MODE``.
+   Read ``rsync(1)`` for more details.
+
+options
+   Defaults to ``--recursive --links --perms --times``.
+   Due to `bug in Python's argparse<https://bugs.python.org/issue9334>`_, value must be prefixed with ``\``.
 
 remote-user
-    Use this user instead of the default "root" for rsync operations.
+   Defaults to ``root``.
 
 
 OPTIONAL MULTIPLE PARAMETERS
 ----------------------------
-rsync-opts
-    Use this option to give rsync options with.
-    See rsync(1) for available options.
-    Only "--" options are supported.
-    Write the options without the beginning "--"
-    Can be specified multiple times.
-
-
-MESSAGES
---------
-NONE
+option
+   Pass additional options to ``rsync``.
+   See ``rsync(1)`` for all possible options.
+   Due to `bug in Python's argparse<https://bugs.python.org/issue9334>`_, value must be prefixed with ``\``.
