# Please view me with 4 column tabs!

# =========================================================================
# User controlled parameters for usage in /etc/make.conf:
#
#  DEFAULT_VERSIONS  - define the default apache version
#                      valid args: apache=2.2, apache=2.4
#
#  APACHE_PORT       - use www/apache22-(event|itk|peruser|worker)-mpm
#                      instead www/apache22.  Use this parameter only in
#                      combination with "DEFAULT_VERSIONS+= apache=2.2"
#
# Example entry in /etc/make.conf:
# - Set apache22 as default version
#    DEFAULT_VERSIONS+= apache=2.2
#
# - Additional use a special www/apache22-$MPM port
#    APACHE_PORT= www/apache22-event-mpm
#
# Note:
#  - This parameters should never be used in the Makefile of a port!
#  - To get a list of "possible" APACHE_PORT values execute the command:
#    $> awk '/apache22-/ {print "www/" $3}' ports/www/Makefile
#
# =========================================================================
#
# This script will be included if one of the following parameter
# is defined in the Makefile of the port
#
# USE_APACHE         - Set apache and apxs as build and run dependency
# USE_APACHE_BUILD   - Set apache and apxs as build dependency
# USE_APACHE_RUN     - Set apache and apxs as run dependency
#
# The following example is representative of all three possible
# parameters to use.
#
# Examples:
#  USE_APACHE= 22       # specify exact version
#  USE_APACHE= 22+      # specify [min] version, no [max] version
#  USE_APACHE= 22-24    # specify [min]-[max] range
#  USE_APACHE= -22      # specify [max] version, no [min] version
#
# Note:
#  - If "+" is specified and no apache is installed, then
#    ${DEFAULT_APACHE_VERSION} will be used.
#
#  - Valid version numbers are specified in the variable
#    APACHE_SUPPORTED_VERSION below
#
#  - The following values for USE_APACHE are reserverd and only valid
#    in apache-server ports!
#      USE_APACHE= common22
#
#
# The following variables can be used (ro) in ports Makefile
# =========================================================================
#  - APACHE_VERSION
#  - APACHEETCDIR
#  - APACHEINCLUDEDIR
#  - APACHEMODDIR
#  - DEFAULT_APACHE_VERSION
#
#
# Parameters for building third party apache modules:
# =========================================================================
#  - AP_FAST_BUILD      # automatic module build
#
#  - AP_GENPLIST        # automatic PLIST generation plus add
#                       # the module disabled into httpd.conf
#                       # (only if no pkg-plist exist)
#
#  - MODULENAME         # default: ${PORTNAME}
#  - SHORTMODNAME       # default: ${MODULENAME:S/mod_//}
#  - SRC_FILE           # default: ${MODULENAME}.c
