   so in general you can't use them in the VM image.
   Similarly, you can't include pay-per-user software such as Matlab in the VM image.
-
  * !VirtualBox runs only on Intel-compatible processors.
   If you want to support other processors (such as ARM, SPARC, etc.),
   you'll need to use non-VM-based app versions.
-
  * Currently you can't run GPU applications in !VirtualBox VMs.
   This may change in the future.

    vboxwrapper sends a [TrickleApi trickle-up message] whose variety is the filename
    and whose contents is the contents of the file, then deletes the file.
- '''completion_trigger_file''':: if vboxwrapper finds a file of this name in the shared directory,

-   The file can optionally contain an integer exit code (first line)

-   This is a workaround for a problem where VMs don't exit cleanly.
+ '''completion_trigger_file'''::
+   This provides a more bulletproof way for VM apps to exit;
+   sometimes VMs fail to shut down, and the task hangs indefinitely.
+   When the VM app is done, it writes a file of this name in the shared directory;
+   the file can optionally contain an integer exit code (first line)
+   and stderr text (subsequent lines).
+   If vboxwrapper finds this file,
+   it cleans up the VM and exits with the given code (default 0).
  '''minimum_checkpoint_interval''':: minimum number of seconds before a checkpoint/snaposhot can be created.
   Defaults to 10 minutes. (v26086+)
