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