compile(+File,+Module)

+File

Atom or string, or list of atoms or strings.

+Module

Atom.

Description

If the file contains no module/1 or module/3 directive, procedures that occur in File are written to the module Module (overwiting if necessary); the rest of the module remains unchanged. If the file contains a module directive it works like compile/1.

If Module does not exist, compile/2 will create such a module and compile File into it.
