 *Also note that this version is not fully compatible with 0.2.x and earlier versions of this plugin. The main difference is that `ls *.dcm | dcm name` doesn't work anymore.
 Use `ls *.dcm | dcm`, `ls *.dcm | get name` or `ls *.dcm | select name type | dcm` instead. `dcm name` is now reserved for the future to select dicom tags.*

 This plugin is in the early stage of the development. It is usable but it might not be able to cope
 with all DICOM objects or DICOMweb records. See [Known limitations for details](#known-limitations).
