29 | * This class proivdes various helper functions for locating extensions | |
30 | * data. It's designed for compatibility with pre-existing functions from | |
31 | * CRM_Core_Extensions. | |
32 | * | |
33 | * Most of these helper functions originate with the first major iteration | |
34 | * of extensions -- a time when every extension had one eponymous PHP class, | |
35 | * when there was no PHP class-loader, and when there was special-case logic | |
36 | * sprinkled around to handle loading of "extension classes". | |
37 | * | |
38 | * With module-extensions (Civi 4.2+), there are no eponymous classes -- | |
39 | * instead, module-extensions follow the same class-naming and class-loading | |
40 | * practices as core (and don't require special-case logic for class | |
41 | * loading). Consequently, the helpers in here aren't much used with | |
42 | * module-extensions. | |
43 | * | |
