34
35The first usage is for creating a new build directory. In this case, the
36script creates the build directory <build-dir>, configures it for the
37specified <machine> and <distro>, and prepares the calling shell for running
38bitbake on the build directory.
39
40The second usage is for using an existing build directory. In this case,
41the script prepares the calling shell for running bitbake on the build
42directory <build-dir>. The build directory configuration is unchanged.
