-
-An example which implements a minimal server-side script.
-
-1) This script expects to find a *.txt file in the .upload_files dir which is
-printed to stdout.
-
-2) It executes a "Count stars" query and prints the result to stdout.
-
-3) It will return with code 0 if everything is ok, or with any code that is
-specified with the commandline option --exit
