Source Modules - part-cw/lambdanative GitHub Wiki
Modules are located in the ./modules framework subdirectory, and offer a simple way to modularize code and share it between applications.
To create a module, add a directory to ./modules/ with the desired module name, e.g.
$ mkdir ./modules/mymodule
and create a source file of the same name in this directory, e.g. mymodule.scm:
$ cat ./modules/mymodule/mymodule.scm
(define (myfunction)
(for-each display (list "This is my " 1 "st module" "\n")))
The module code can now be included in the framework applications by adding its name to the MODULES file in the application directories.
