-# Generates a header with preprocessor defines specified by the build file.
-#
-# The canonical documentation is in build/buildflag_header.gni. You should
-# write the GN build, get it working, and then transform it into GYP.
-#
-# In every target that uses your generated header you must include a dependency
-# on the GYP target that generates the header (this is implicit in GN).
-# Otherwise, clean builds may not necessarily create the header before the
-# source code is compiled.
-#
-# Assuming your GN code looks like this:
-#
-#   buildflag_header("foo_features") {
-#     header = "foo_features.h"
-#     flags = [
-#       "ENABLE_DOOM_MELON=$enable_doom_melon",
-#       "ENABLE_SPACE_LASER=true",
-#       "SPAM_SERVER_URL=\"http://www.example.com/\"",
-#     ]
-#   }
-#
-# Write a GYP target like this:
-#
-#  {
-#    # GN version: //foo:foo_features
-#    'target_name': 'foo_foo_features',
-#    'includes': [ '../build/buildflag_header.gypi' ],
-#    'variables': {
-#       'buildflag_header_path': 'foo/foo_features.h',
-#       'buildflag_flags': [
-#         'ENABLE_DOOM_MELON=<(enable_doom_melon)',
-#         'ENABLE_SPACE_LASER=true',
-#         'SPAM_SERVER_URL="http://www.example.com/"',
-#       ],
-#     },
-#   }
-#
-# Variables
-#
-#   target_name
-#       Base this on the GN label, replacing / and : with _ to make it globally
-#       unique.
-#
-#   buildflag_header_path
-#       This must be the full path to the header from the source root. In GN
-#       you only say "features.h" and it uses the BUILD file's path implicitly.
-#       Use the path to BUILD.gn followed by your header name to produce the
-#       same output file.
-#
-#   buildflag_flags (optional)
-#       List of the same format as GN's "flags". To expand variables, use
-#       "<(foo)" where GN would have used "$foo".
-#
-#   includes
-#       List the relative path to build/buildflag_header.gypi from the .gyp
-#       file including this code, Note: If your code is in a .gypi file in a
-#       different directory, this must be relative to the .gyp including your
-#       file.
-#
-#
-# Grit defines
-#
-# Follow the same advice as in the buildflag_header.gni, except on the grit
-# action use the variable name 'grit_additional_defines' and explicitly add a
-# '-D' in front:
-#
-#   'grit_grd_file': 'foo.grd',
-#   'grit_additional_defines': [
-#     '-D', 'enable_doom_melon=<(enable_doom_melon)',
-#    ],
-#
-# Put shared lists of defines in a .gypi.
