2DESCRIPTION = "The GNU Binutils are a collection of binary tools. \
3The main ones are ld (GNU Linker), and as (GNU Assembler). This \
4package also includes addition tools such as addr2line (Converts \
5addresses into filenames and line numbers), ar (utility for creating, \
6modifying and extracting archives), nm (list symbols in object \
7files), objcopy (copy and translate object files), objdump (Display \
8object information), and other tools and related libraries."
