+# Rule to extract integer values for each symbol from an object file.
+# The output file name is the input file name with extension replaced with
+# asm or h.
+# The following gyp variables must be set before including this gypi:
+#   output_format, the output format of integer value.
+#   output_dir, the full path where the output file should be created.
+#
+# For example:
+#
+# 'sources': ['a.o', 'b.o'],
+# 'variables': {
+#   'output_format': 'cheader',
+#   'output_dir': 'output',
+# },
+# 'includes': ['obj_int_extract.gypi'],
+#
+# This extracts the symbol from a.o and b.o, and outputs them to a.h and b.h
+# in output directory.
