+# cdist
+
+**cdist** is a usable configuration management system.
+
+It adheres to the [**KISS principle**](https://en.wikipedia.org/wiki/KISS_principle)
+and is being used in small up to enterprise grade environments.
+
+For more information have a look at [**homepage**](https://cdi.st)
+or at **``docs/src``** for manual in **reStructuredText** format.
+
+## Contributing
+
+Merge/Pull requests can be made in both
+[upstream **GitLab**](https://code.ungleich.ch/ungleich-public/cdist/merge_requests)
+(managed by [**ungleich**](https://ungleich.ch))
+and [**GitHub** project](https://github.com/ungleich/cdist/pulls).
+
+Issues can be made and other project management activites happen
+[**only in GitLab**](https://code.ungleich.ch/ungleich-public/cdist)
+(needs [**ungleich** account](https://account.ungleich.ch)).
+
+For community-maintained types there is
+[**cdist-contrib** project](https://code.ungleich.ch/ungleich-public/cdist-contrib).

+=======================
+
+NAME
+----
+cdist-type__download - Download file to local storage and copy it to target host
+
+
+DESCRIPTION
+-----------
+You must use persistent storage in target host for destination file
+(``$__object_id``) because it will be used for checksum calculation
+in order to decide if file must be downloaded.
+
+
+REQUIRED PARAMETERS
+-------------------
+url
+   URL from which to download the file.
+
+sum
+   Checksum of downloaded file.
+
+
+OPTIONAL PARAMETERS
+-------------------
+cmd-get
+   Command used for downloading.
+   Default is ``wget -O- '%s'``.
+   Command must output to ``stdout``.
+
+cmd-sum
+   Command used for checksum calculation.
+   Default is ``md5sum '%s' | awk '{print $1}'``.
+   Command output and ``--sum`` parameter must match.
+
+
+EXAMPLES

+   is checked out.
+
 recursive
    Passes the --recurse-submodules flag to git when cloning the repository.
 
 shallow
    Sets --depth=1 and --shallow-submodules for cloning repositories with big history.
