12 ## This file assembles changes to existing Apache source files
13 ## between the original Apache and the patched variant. It can be
14 ## automatically applied to a vanilla Apache source tree with the
15 ## 'patch' tool to upgrade those files. Each patch snippet is
16 ## annotated with a short description.
18 ## This file contains all patches to the Apache source
19 ## tree which add the Extended API (EAPI) support.

313 + * structure is kicked out from the Apache internal module list.

315 + * consistency with the add_module hook.
318 + * Called right after a configuration directive line was read and
319 + * before it is processed. It is mainly intended to be used for

321 + * old directive variants.

326 + * created and before Apache starts processing the request with
