This function first looks in the current working directory for a file named Emakefile (see below) specifying the set of modules to compile and the compile options to use. If no such file is found, the set of modules to compile defaults to all modules in the current working directory. Traversing the set of modules, it then recompiles every module for which at least one of the following conditions apply:

• there is no object file, or
• the source file has been modified since it was last compiled, or,
• an include file has been modified since the source file was last compiled.

As a side effect, the function prints the name of each module it tries to compile. If compilation fails for a module, the make procedure stops and error

is returned. Options is a list of make- and compiler options. The following make options exist:

• noexec
  No execution mode. Just prints the name of each module that needs to be compiled.
• load
  Load mode. Loads all recompiled modules.
• netload
  Net load mode. Loads all recompiled modules an all known nodes.

All items in Options that are not make options are assumed to be compiler options and are passed as-is to compile:file/2. Options defaults to [].
