#
#  Updates the version string for ES-DE.
#  This script takes as arguments the major, minor and patch numbers as well as an optional
#  alphanumeric suffix and updates all the necessary files to indicate a new software version.
#  The script has to be run from within the tools directory.
#
#  Example use:
#  ./update_version_string.sh 2 1 0 beta
#
#  The following files are updated by this script:
#  es-app/CMakeLists.txt
#  es-app/src/ApplicationVersion.h
#  es-app/assets/ES-DE.plist
#  es-app/assets/Windows_Portable_README.txt
#
#  This script is only intended to be used on Linux systems.
