   3 # This script takes rpm package files, finds *.so.N files in them,
   4 # and runs objdump --dynamic-syms on them.  The arguments are rpm file
   5 # names.  For each rpm, it creates an output file with the name
   6 # "NAME-VERSION-RELEASE.ARCH.dynsym", the variable parts being extracted
   7 # from the rpm's headers (not its file name).  Each file contains the
   8 # collected objdump output for all the *.so.N files in the corresponding rpm.
   9 # This can be processed with abilist.awk or sent to someone who will do that.
  10 # This does not do a lot of error-checking, so you should always watch stderr
  11 # and sanity-check the resulting output files.
