- Initialize an "enterprise" folder that is copyrighted. - You can remove this folder and the system will continue functioning normally, in case you want a purely MIT licensed product. - Enable limit on the number of user accounts in enterprise code. - Use enterprise edition injector methods (inspired from Gitlab). - SaaS software would run enterprise edition software always.

# Ancestors chain : it holds a list of constant names which are its ancestors
|
|
# example, by calling ancestors on the String class,
|
|
# String.ancestors => [String, Comparable, Object, PP::ObjectMixin, Kernel, BasicObject]
|
|
#
|
|
# Include: Ruby will insert the module into the ancestors chain of the class, just after its superclass
|
|
# ancestor chain : [OriginalClass, IncludedModule, ...]
|
|
#
|
|
# Extend: class will actually import the module methods as class methods
|
|
#
|
|
# Prepend: Ruby will look into the module methods before looking into the class.
|
|
# ancestor chain : [PrependedModule, OriginalClass, ...]
