# Even though this is called "install-apache", it doesn't really
# install the whole thing.  Much of apache itself is installed by
# make install - we need to fix permissions.  What we install here
# are modules that apache won't install as part of its normal build.
# Each install task is a function, so it's relatively easy to add new
# stuff.
