"""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.
