A collection of classes that can be used across yestech artifacts/components, but must not be dependant on any yestech component. Most of the code is utility type code. When more than a few classes are found to be in a package or the package start to handle more that a few reposibilities then a new independant component is created and the existing code in yeslib is ported to the new component.

There is a newer version: 1.2.0
