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