 Sometimes it's desirable to build a subset of targets, without having to
 list out each individual one. For example if you wanted to build and run
 all the unit tests in the `TEST_POSIX` package, you could say:
 
 ```sh
-build/bootstrap/make.com o//test/posix
+build/bootstrap/make o//test/posix
 ```
 
 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.
 
 ```sh
-build/bootstrap/make.com m=tinylinux
+build/bootstrap/make m=tinylinux
 ```
