additional modules, including modules that you compiled locally, can
be specified with this flag. Any number of modules can be loaded, and
they will be linked in the order they are listed on the command line.
Normally, you only need to specify the name of the module, without any
directory path or .vpi suffix and the search path is scanned to find
the module. However, if the name includes at least one directory
character, then the search path is not scanned and the name is assumed
to be a complete file name.
