# apxs, apr-config, and apu-config are Apache utilities used      #
# to both get certain configuration information and also to       #
# assist in building Apache modules. These utilities have not     #
# yet been officially ported to Win32. The following will fetch   #
# and install a development version of these scripts which can    #
# be used in both mod_perl 2 and Apache C modules.                #
#                                                                 #
# Please report problems in installing or using these utilties to #

----------------------------------------------------------------------
I could not find an apxs utility, which will be used in certain parts 
of the build, if present. This utility (and the apr-config and 
apu-config utilities) have not yet been ported to Apache2 on Win32, 
but a development port is available. You can either

- ignore installing apxs by answering "no" at the prompt below
  (mod_perl will still build),
- install apxs by answering "yes" at the prompt below,
- quit now, run the "fetch_win32_apxs.pl" script in the build/ directory 
  to fetch and install the utilities, and then rebuild mod_perl,
- quit now, and from https://apache.org/dist/perl/win32-bin/ grab 
  apxs_win32.tar.gz; when unpacked, this contains a README explaining 
  how to install the utilities. Afterwards, rebuild mod_perl.
