Qore modules allow the Qore language to be extended at run-time. Qore modules must conform to the Qore Module API and have the file extension *.qmod. Qore modules normally depend on other shared libraries and therefore can only be loaded if the libraries they require are present on the system and can be found in the library path.

Please note that as of version 0.7.0 onwards, modules are no longer delivered with the Qore library. Modules must be downloaded separately; see Qore's home page for more information.

To load a module at parse time (normally required for most modules), use the %requires parse directive. If the named feature is not already present in Qore, Qore looks for a module with this name in the directories listed in the QORE_MODULE_DIR environment variable.

Use the load_module() function to load Qore modules at run-time; however, note that any module providing parse support (classes, constants, functions, etc) must be loaded at parse time using the %requires directive.

From Qore 0.7.1 onwards, you can specify a comparison operator (one of < <=, =, >=, or >) and version information after the module name as well. Version numbers are compared via integer comparisons of each element, where elements are separated by a '.'. If one of the versions does not have as many elements as another, the missing elements are assumed to be '0' (i.e. version "1.0" compared with version "1.0.1" will be exteneded to "1.0.0").

Also note that DBI drivers are loaded on demand by the Datasource and DatasourcePool classes.
