Compiles the given files.

Those files are compiled in parallel and can automatically detect dependencies between them. Once a dependency is found, the current file stops being compiled until the dependency is resolved.

If there is an error during compilation or if warnings_as_errors is set to true and there is a warning, this function will fail with an exception.

This function accepts the following options:

• :each_file - for each file compiled, invokes the callback passing the file

• :each_module - for each module compiled, invokes the callback passing the file, module and the module bytecode

• :dest - the destination directory for the beam files. When using files/2, this information is only used to properly annotate the beam files before they are loaded into memory. If you want a file to actually be written to dest, use files_to_path/3 instead.

Returns the modules generated by each compiled file.

Compiles the given files to the given path. Read files/2 for more information.
