Use Case files

The use case files of KEEL provides valuable information to understanding every of the methods which are available to use. They are XML files, located in the ../dist/help directory.

Each KEEL use case file is composed by 4 sections:

Use case structure
The name of the method.
A list of references associated with the method.
General Description
Generic information about the method.
A example about the use of the method.


The first part of the use case contains the name of the method, enclosed by <name> tags:
