This makes sense because with debuginfod none of the positional parameters are needed. However it means that users having debuginfod-find installed will have no chance of reading the usage text without opening the file. Many programs have a '-h' flag to get the usage, so add such a flag. Invoking 'scripts/decode_stacktrace.sh -h' will now show the usage text and exit.
