build-with-curl-json.sh

#!/bin/bash
##
# Script to send the BASIC file to the service using the curl to send the binary
# to the service, and retrieve a build result as structured data.
#
# This example code requires:
#
#   curl
#   jq
#   sed
#   base64
#
# The submission code examples come from here:
#
#   https://build.riscos.online/ci-build.html#curl
#
# The result comes out as JSON, which is described under the JSON API, here:
#
#   https://build.riscos.online/api.html
#
# Syntax: build-with-curl-json.sh [<input-file> [<output-prefix>]]
