+# Usage:
+#   setup-ubase install [-d <dest>] [-f] [-v] [<applet>...]
+#   setup-ubase uninstall [-d <dest>] [-v] [<applet>...]
+#   setup-ubase status [-d <dest>]
+#   setup-ubase (-h | -V)
+#
+# Install or uninstall applet symlinks for ubase-box.
+#
+# Arguments:
+#   <applet>   Name of the applet(s) to (un)install or show status for.
+#              Defaults to all ubase-box applets.
+#
+# Options:
+#   -d <dest>  Path to directory where to install ubase symlinks. If not given,
+#              symlinks are created in the same directories as busybox symlinks
+#              (if busybox is installed, otherwise /usr/bin).
+#   -f         If the symlink destination exists, replace it.
+#   -v         Be verbose.
+#   -h         Show this message and exit.
+#   -V         Print ubox version and exit.
