# Pre-requisites:
# - bash shell (for Windows: install git for Windows)
# - 7z in path (zip archiving utility)
#   e.g. Ubuntu: sudo apt-get install p7zip-full p7zip-rar) 
# - PackChk in path with execute permission
#   (see CMSIS-Pack: CMSIS/Utilities/<os>/PackChk)
# - xmllint in path (XML schema validation; available only for Linux)
