+# Run this script to regenerate descriptor.pb.{h,cc} after the protocol
+# compiler changes.  Since these files are compiled into the protocol compiler
+# itself, they cannot be generated automatically by a make rule.  "make check"
+# will fail if these files do not match what the protocol compiler would
+# generate.
+
+# Note that this will always need to be run once after running
+# extract_from_google3.sh.  That script initially copies descriptor.pb.{h,cc}
+# over from the google3 code and fixes it up to compile outside of google3, but
+# it cannot fix the encoded descriptor embedded in descriptor.pb.cc.  So, once
+# the protocol compiler has been built with the slightly-broken
+# descriptor.pb.cc, the files must be regenerated and the compiler must be
+# built again.
