/**
* Dependency Manager "dm" command. We use gogo annotations, in order to automate documentation,
* and also to automatically manage optional flags/options and parameters ordering.
*
* @param session the gogo command session, used to get some variables declared in the shell
* This parameter is automatically passed by the gogo runtime.
* @param nodeps false means that dependencies are not displayed
* @param compact true means informations are displayed in a compact format. This parameter can also be
* set using the "dependencymanager.compact" gogo shell variable.
* @param notavail only unregistered components / unavailable dependencies are displayed
* @param stats true means some statistics are displayed
* @param services an osgi filter used to filter on some given osgi service properties. This parameter can also be
* set using the "dependencymanager.services" gogo shell variable.
* @param components a regular expression to match either component implementation class names. This parameter can also be
* set using the "dependencymanager.components" gogo shell variable.
* @param componentIds only components matching one of the specified components ids are displayed
* @param bundleIds a list of bundle ids or symbolic names, used to filter on some given bundles
