-"""Pack relocations in a library (or copy unchanged).
-
-If --enable-packing and --configuration-name=='Release', invoke the
-relocation_packer tool to pack the .rel.dyn or .rela.dyn section in the given
-library files.  This step is inserted after the libraries are stripped.
-
-If --enable-packing is zero, the script copies files verbatim, with no
-attempt to pack relocations.
-
-Any library listed in --exclude-packing-list is also copied verbatim,
-irrespective of any --enable-packing setting.  Typically this would be
-'libchromium_android_linker.so'.
