 Usage: $SCRIPTNAME [OPTION]... [EXTRA_CONFIGURE_ARG]...
 Options:
-  --arch=ARCH                Specify the architecture.  The default is taken
-                                 from MSYSTEM if available, otherwise is x86_64.
-  --install-msys2-packages   Install prerequisite MSYS2 packages
-  --no-docs                  Don't build and install PDF manual pages
-  --no-zip                   Don't create the final zip file
+  --arch=ARCH               Specify the CPU architecture.  This is unnecessary
+                            when using MSYS2.
+
+  --include-docs            Build and install the PDF manual pages.
+
+  --install-msys2-packages  Install the MSYS2 packages needed to build wimlib.
+                            You can omit this if you have already done this for
+                            the same MSYS2 environment.
+
+  --skip-configure          Skip running the configure script again.  You can
+                            use this to save time in incremental builds if you
+                            are sure you didn't change any options.
+
+  --zip                     Zip the output files up into a zip file.
