+                            Display this help and exit.

+    --sleeptime [T] | -s [T]
+                            How long to sleep between each build attempt in seconds. The
+                            time defaults to 10 seconds.
+ARGUMENTS:
+    READER := [[echo "\${READER-zathura}"]]
+                            The reader to open the build PDF with.
