[__unpack] no mkdir by default, because destination can be file, but tar needs mkdir andrar needs slash at the end

+cdist-type__unpack(7)
+=====================
+
+NAME
+----
+cdist-type__unpack - Unpack archives
+
+
+DESCRIPTION
+-----------
+Unpack ``.tar``, ``.tgz``, ``.tar.*``, ``.7z``, ``.bz2``, ``.gz``,
+``.lzma``, ``.xz``, ``.rar`` and ``.zip`` archives. Archive type is
+detected by extension.
+
+To achieve idempotency, checksum file will be created in target. See
+``--sum-file`` parameter for details.
+
+
+REQUIRED PARAMETERS
+-------------------
+destination
+   Depending on archive format file or directory to where archive
+   contents will be written.
+
+
+OPTIONAL PARAMETERS
+-------------------
+sum-file
+    Override archive's checksum file in target. By default
+    ``XXX.cdist__unpack_sum`` will be used, where ``XXX`` is source
+    archive path. This file must be kept in target's persistent storage.
+
+tar-strip
+    Tarball specific. See ``man tar`` for ``--strip-components``.
+
+
+OPTIONAL BOOLEAN PARAMETERS
+---------------------------
+backup-destination
+    By default destination file will be overwritten. In case destination
+    is directory, files from archive will be added to or overwritten in
+    directory. This parameter moves existing destination to
+    ``XXX.cdist__unpack_backup_YYY``, where ``XXX`` is destination and
+    ``YYY`` current UNIX timestamp.
+
+preserve-archive
+    Don't delete archive after unpacking.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    __directory /opt/cpma
+
+    require='__directory/opt/cpma' \
+        __download /opt/cpma/cnq3.zip \
+            --url https://cdn.playmorepromode.com/files/cnq3/cnq3-1.51.zip \
+            --sum md5:46da3021ca9eace277115ec9106c5b46
+
+    require='__download/opt/cpma/cnq3.zip' \
+        __unpack /opt/cpma/cnq3.zip \
+            --backup-destination \
+            --preserve-archive \
+            --destination /opt/cpma/server
