A module is usually composed of two files. One file is the binary library module with the extension .dll under Windows NT or .so under Unix. The other file is an include file, which contains the declare sub statement for each external function.
To install a module you have to copy or move the module binary to one of the directories specified in the configuration file as ScriptBasic module directory and you have to copy or move the include file into one of the directories specified in the configuration file as ScriptBasic include directory.
The basic program that uses the module includes the include file and it is ready to call the functions declared in that file. Currently there are no install programs available that place the file at the appropriate locations.
