-file pnglibconf.h scripts/pnglibconf.dfa PNGLCONF_H
-
-# This file is preprocessed by scripts/options.awk and the
-# C compiler to generate 'pnglibconf.h' - a list of all the
-# configuration options.  The file lists the various options
-# that can *only* be specified during the libpng build;
-# pnglibconf.h freezes the definitons selected for the specific
-# build.
-#
-# The syntax is detailed in scripts/options.awk, this is a summary
-# only:
-#
-# setting <name> [requires ...] [default]
-#    #define PNG_<name> <value>  /* value comes from current setting */
-# option <name> [requires ...] [if ...] [enables ...] [disabled]
-#    #define PNG_<name>_SUPPORTED if the requirements are met and
-#    enable the other options listed
-# chunk <name> [requires ...] [disabled]
-#    Enable chunk processing for the given ancillary chunk
-#
-# Note that the 'on' and 'off' keywords, while valid on both option
-# and chunk, should not be used in this file because they force the
-# relevant options on or off.
-
-#----------------------------------------------------------------------
-
-# The following setting, option and chunk values can all be changed
-# while building libpng:
-# 
-# setting: change 'setting' lines to fine tune library performance,
-#   changes to the settings don't affect the libpng API functionally
-#
-# option: change 'option' lines to remove or add capabilities from
-#   or to the library; options change the library API
-#
-# chunk: change 'chunk' lines to remove capabilities to process
-#   optional ('ancillary') chunks.  This does not prevent PNG
-#   decoding but does change the libpng API because some chunks
-#   will be ignored.
-#
-# There are three ways of disabling features, in no particular order:
-#
-# 1) Create 'pngusr.h', enter the required private build information
-# detailed below and #define PNG_NO_<option> for each option you
-# don't want in that file in that file.  You can also turn on options
-# using PNG_<option>_SUPPORTED.  When you have finished rerun
-# configure and rebuild pnglibconf.h file with -DPNG_USER_CONFIG:
-# 
-#  make clean
-#  CPPFLAGS='-DPNG_USER_CONFIG' ./configure
-#  make pnglibconf.h
-#
-# pngusr.h is only used during the creation of pnglibconf.h, but it
-# is safer to ensure that -DPNG_USER_CONFIG is specified throughout
-# the build by changing the CPPFLAGS passed to the initial ./configure
-#
-# 2) Add definitions of the settings you want to change to
-# CPPFLAGS; for example:
-# 
-#   -DPNG_DEFAULT_READ_MACROS=0
-#
-# (This would change the default to *not* use read macros.)  Be
-# very careful to change only settings that don't alter the API
-# because this approach bypasses the private build checking.  You
-# can also change settings from pngpriv.h (read pngpriv.h) safely
-# without API changes.  Do that in the same way.
-#
-# 3) Write a new '.dfa' file (say 'pngusr.dfa') and in this file
-# provide override values for setting entries and turn option or
-# chunk values explicitly 'on' or 'off':
-#
-#    setting FOO default VALUE
-#    option BAR [on|off]
-#
-# Then add this file to the options.awk command line (the *first*
-# one) after this file.  The make macro DFA_XTRA is provided to make
-# this easier (set it like CPPFLAGS prior to running ./configure).
-# Look at the builds below contrib/pngminim for some extreme examples
-# of how this can be used.
-#
-# Don't edit this file unless you are contributing a patch to
-# libpng and need new or modified options/settings.
-#----------------------------------------------------------------------
-
-# The following causes commented out #undef lines to be written to
-# pnglibconf.h; this can be stopped by logunsupported=0 in a later
-# file or on the command line (after pnglibconf.dfa)
-
-logunsupported = 1
-
-# PNG_USER_CONFIG has to be defined on the compiler command line
-# to cause pngusr.h to be read while constructing pnglibconf.h
-#
-# If you create a private DLL you need to define the following
-# macros in the file 'pngusr.h' and set -DPNG_USER_CONFIG for
-# compilation (i.e. in CFLAGS.)
-# #define PNG_USER_PRIVATEBUILD \
-#     <Describes by whom and why this version of the DLL was built>
-#  e.g. #define PNG_USER_PRIVATEBUILD "Build by MyCompany for xyz reasons."
-# #define PNG_USER_DLLFNAME_POSTFIX <two-letter postfix that serve to
-#        distinguish your DLL from those of the official release. These
-#        correspond to the trailing letters that come after the version
-#        number and must match your private DLL name>
-#  e.g. // private DLL "libpng13gx.dll"
-#       #define PNG_USER_DLLFNAME_POSTFIX "gx"
-#
-# The following macros are also at your disposal if you want to complete the
-# DLL VERSIONINFO structure.
