   3 # Run this script to regenerate descriptor.pb.{h,cc} after the protocol
   4 # compiler changes.  Since these files are compiled into the protocol compiler
   5 # itself, they cannot be generated automatically by a make rule.  "make check"
   6 # will fail if these files do not match what the protocol compiler would
   7 # generate.

   9 # Note that this will always need to be run once after running
  10 # extract_from_google3.sh.  That script initially copies descriptor.pb.{h,cc}
  11 # over from the google3 code and fixes it up to compile outside of google3, but
  12 # it cannot fix the encoded descriptor embedded in descriptor.pb.cc.  So, once
  13 # the protocol compiler has been built with the slightly-broken
  14 # descriptor.pb.cc, the files must be regenerated and the compiler must be
  15 # built again.
