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. | |
17 | ## | |
18 | ## This file contains all patches to the Apache source | |
19 | ## tree which add the Extended API (EAPI) support. | |

39 | +# EAPI_MM: | |
40 | +# Set the EAPI_MM variable to either the directory of a MM Shared Memory | |
41 | +# Library source tree or the installation tree of MM. Alternatively you can | |
42 | +# also use the value 'SYSTEM' which then indicates that MM is installed | |
43 | +# under various system locations. When the MM library files cannot be found | |
