In OSE run_erl and to_erl are combined into a single load module called run_erl_lm. Installing and starting the load module will add two new shell commands called run_erl and to_erl. They work in exactly the same way as the unix variants of run_erl and to_erl, except that the read and write pipes have to be placed under the /pipe vm. See also run_erl for more details.
