+This script will either build:
+ * A single file executable named dist/novelWriter.exe. This is a quite
+   slow option, and the file is fairly big. Option --onefile
+ * A single directory named dist/novelWriter with a novelWriter.exe, and
+   all dependecies included. This is the default.
+ * The latter can be combined with a build stage of a setup.exe file
+   named setup-novelwriter-<version>.exe. Option --setup.
+
+In addition, providing the --pip flag will cause the script to try to
+install all dependencies needed for runing the build, and for running
+novelWriter itself.
