# is honored, so we can use ccache or an equivalent tool.

# 'BUILD.gn' was generated as follows (using GNU sed):
#
#   (echo -e '# Automatically generated. See mods.gni.\n' |
#    cat - ../../../build/toolchain/win/BUILD.gn          |
#    sed '0,/import/s|import|import("mods.gni")\n&|'      |
#    sed 's|exec_script("|&$base_toolchain_dir/|'         |
#    sed 's|${goma_prefix}|&${cc_wrapper_prefix}|'        ) > BUILD.gn
#   gn format BUILD.gn

# Ensure the 'cc_wrapper' variable is in scope.
