#================================================================
# # About
# This script replaces $(SolutionDir) in the reference paths of the supplied
# project file with the specified directory.
# If the supplied argument is a directory then the first vcxproj found
# in the directory will be used.
# Result is output to OUTPUT_FILE.
#
# # Arguments
# [1] PROJECT_PATH - vcxproj file or directory containing vcxproj file.
# [2] F4SE_HOME - Location of the src/f4se/ directory.
# [3] OUTPUT_FILE - vcxproj will be output here.
#================================================================

# Configuration
