+* Overview
+
This directory includes an example program for extending Guile with a
new (and even useful) data type, putting it into a shared library, so it
can be called from an unmodified guile interpreter. Further, the shared
library defines a new guile module.
+
+* Build Instructions
+
To build the example, simply type
make libbox-module
in this directory.
+
+* The Box Data Type
+
A box is simply an object for storing one other object in. It can be
used for passing parameters by reference, for example. You simply
store an object into a box, pass it to another procedure which can
store a new object into it and thus return a value via the box.
+
+** Usage
+
Box objects are created with `make-box', set with `box-set!' and
examined with `box-ref'. Note that these procedures are placed in a
module called (box-module) and can thus only be accessed after using
-this module. See the following example session for usage details:
+this module. See the following example session for usage details.
+
+** The Module (box-module)
+
Extend your LD_LIBRARY_PATH variable (or equivalent) to include . and
.libs and make sure that your current working directory is the one
this file is contained in.
-If you like this example so much that you want to have it available
-for normal usage, install the dynamic libraries in the .libs directory
-to the directory $(prefix)/lib and the scheme file `box-module.scm' in
-a directory in your GUILE_LOAD_PATH.

+The following example uses the module (box-mixed), also included in
+this directory. It uses the shared library libbox-module like the
+module (box-module) above, but does not export the procedures from
+that module. It only implements some procedures for dealing with box
+objects.
