+Generate a graph of the current DAPM state for an audio card.
+
+The DAPM state can be obtained via debugfs for a card on the local host or
+a remote target, or from a local copy of the debugfs tree for the card.
+
+Usage:
+    $(basename $0) [options] -c CARD                  - Local sound card
+    $(basename $0) [options] -c CARD -r REMOTE_TARGET - Card on remote system
+    $(basename $0) [options] -d STATE_DIR             - Local directory
+
+Options:
+    -c CARD             Sound card to get DAPM state of
+    -r REMOTE_TARGET    Get DAPM state from REMOTE_TARGET via SSH and SCP
+                        instead of using a local sound card
+    -d STATE_DIR        Get DAPM state from a local copy of a debugfs tree
+    -o OUT_FILE         Output file (default: dapm.dot)
+    -D                  Show verbose debugging info
+    -h                  Print this help and exit
+
+The output format is implied by the extension of OUT_FILE:
+
+ * Use the .dot extension to generate a text graph representation in
+   graphviz dot syntax.
+ * Any other extension is assumed to be a format supported by graphviz for
+   rendering, e.g. 'png', 'svg', and will produce both the .dot file and a
+   picture from it. This requires the 'dot' program from the graphviz
+   package.
