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

+# EAPI_MM:
+#   Set the EAPI_MM variable to either the directory of a MM Shared Memory

+#   also use the value 'SYSTEM' which then indicates that MM is installed
