System Principles 文档写着：

1.4 Code Loading Strategy

The runtime system can be started in either embedded or interactive mode. Which one is decided by the command line flag -mode.

% erl -mode embedded

Default mode is interactive.

* In embedded mode, all code is loaded during system start-up according to the boot script. (Code can also be loaded later by explicitly ordering the code server to do so).
* In interactive mode, code is dynamically loaded when first referenced. When a call to a function in a module is made, and the module is not loaded, the code server searches the code path and loads the module into the system.

Initially, the code path consists of the current working directory and all object code directories under ROOT/lib, where ROOT is the installation directory of Erlang/OTP. Directories can be named Name[-Vsn] and the code server, by default, chooses the directory with the highest version number among those which have the same Name. The -Vsn suffix is optional. If an ebin directory exists under the Name[-Vsn] directory, it is this directory which is added to the code path.
