+=head1 RUNNING COMMANDS LOCALLY

+Any line which starts with a I<!> character is treated as a command
+sent to the local shell (C</bin/sh> or whatever L<system(3)> uses).
+For example:
+
+ !mkdir local
+ tgz-out /remote local/remote-data.tar.gz

+=head1 EXIT ON ERROR BEHAVIOUR
+
+By default, guestfish will ignore any errors when in interactive mode
+(ie. taking commands from a human over a tty), and will exit on the
+first error in non-interactive mode (scripts, commands given on the
+command line).
+
+If you prefix a command with a I<-> character, then that command will
+not cause guestfish to exit, even if that (one) command returns an
+error.
