-"""Pack ARM relative relocations in a library (or copy unchanged).
-
-If --enable-packing, invoke the relocation_packer tool to pack the .rel.dyn
-section in the given library files.  This step is inserted after the libraries
-are stripped.  Packing adds a new .android.rel.dyn section to the file and
-reduces the size of .rel.dyn accordingly.
-
-Currently packing only understands ARM32 shared libraries.  For all other
-architectures --enable-packing should be set to zero.  In this case the
-script copies files verbatim, with no attempt to pack relative 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'.
