# This is a script for easily building the wownero cli installer in an automated build. Note
# that it is also possible to build the installer by dropping the .nsi file on the NSIS GUI,
# but that this will not work, as the script requires some defines, parsed from the wownero
# version file, to be passed on the command line.
