 Cosmopolitan provides a variety of build modes. For example, if you want
 really tiny binaries (as small as 12kb in size) then you'd say:

 ```sh
-build/bootstrap/make.com m=tiny
+build/bootstrap/make m=tiny
 ```

 You can furthermore cut out the bloat of other operating systems, and
 have Cosmopolitan become much more similar to Musl Libc.
