Module Loading
--------------

   As described above, the common way of loading modules is to use the
`open' and `access' clauses of the configuration language.

   If the modules named by these clauses are not currently loaded into
the interpreter, then the system will attempt to load them from the
filing system, using the standard `load-path' variable to define the
directories to search.

   To allow modules names to be hierarchical, any dot characters in a
module's name are replaced by the operating system's directory
separator string (i.e. on unix, all `.' characters are simply replaced
by `/' characters).

   When searching for files to load, the standard filename suffixes are
used to differentiate Lisp files from other types of files (Note: Load
Function). This file should contain a `define-structure' form (as
described in the previous section) as the last top-level form in the
file.

   For backwards compatibility, the `require' function can also be used
to import modules. If a module of the same name as the requested
feature has already been loaded, then it is imported into the current
module. Otherwise if a file is loaded that contains a module definition
as its last top-level form, this module is imported into the current
module. Note: Features.
