Usage: $0 [options] <new-project.vcxproj> [<new-project-source-file-name>]

Create a new project by copying the minimal sample .vcxproj file to the given
new file and replacing the minimal.cpp with the specified new source file name
(defaults to the project file name).

Options:
    -f, --force         Overwrite the file with the new name even if it exists.
    -v, --verbose       Show more details about what the program is doing.
