* No arguments: Show all packages of all architectures and SDK-levels
=== OR ===
* SDK-level as a argument:  Show packages that are eligable to be picked when building for specified SDK-level
* all|arm|arm64|x86|x86_64: Show only packages of given architecture
* These arguments can be combined in any order and multiple architectures can be supplied
* Example command: './report_sources.sh 22 all arm arm64'
=== OR ===
* (all|arm|arm64|x86|x86_64)-(SDK-level): Show packages that will be selected when building for specified architecture and SDK-level
* Example command: './report_sources.sh arm-22'
=== AND ===
* hash: If you add hash as an extra argument, the result will not be returned as human readable, but with a unique hash for the resultset
* nohelp: If you add nohelp as an extra argument, the result will not include this helptext (not necessary if hash is used)
* nosig: Skips signature checking (which takes a lot of CPU power); NB: this does change the hash result!
* Example command: './report_sources.sh arm-22 hash'
