     Usage:
     To build the library and generate header (.di) files, run
     ---
-    rdmd build
+    ./build
     ---
     To build only the library file, run
     ---
-    rdmd build lib
+    ./build lib
     ---
     To only generate header files, run
     ---
-    rdmd build headers
+    ./build headers
     ---
     To make the documentation, run
     ---
-    rdmd build html
+    ./build html
     ---

     Any command line arguments beyond the first one will be passed
     on to the compiler.  For example, to enable optimisations and
     inlining when building the library, run
     ---
-    rdmd build lib -O -inline
+    ./build lib -O -inline
