+smount
+------
+
+A wrapper around `udisksctl` for mounting volumes without `sudo`. The script
+understands three commands:
+
+ * `mount`
+ * `umount`
+ * no parameter lists all connected devices (a leading `*`) indicates that it
+   is mounted
+
+`mount` and `umount` accept either the block device name or the name of the
+volume (usually the label). It matches the given name case-insensitive.
+
+    $ smount
+    * data        /dev/sdb1
+      usb-stick   /dev/sdc
+    $ smount umount data
+    Unmounted /dev/sdb1
+    $ smount
+      data        /dev/sdb1
+      usb-stick   /dev/sdc3
+    $ smount mount sdc
+    Mounted /dev/sdc3 at /run/media/baldrick/usb-stick.
