-History
--------
-
-Here is a brief project history of the ELF and COFF ports.
-
-- May 2015: We decided to rewrite the COFF linker and did that.
-  Noticed that the new linker is much faster than the MSVC linker.
-
-- July 2015: The new ELF port was developed based on the COFF linker
-  architecture.
-
-- September 2015: The first patches to support MIPS and AArch64 landed.
-
-- October 2015: Succeeded to self-host the ELF port. We have noticed
-  that the linker was faster than the GNU linkers, but we weren't sure
-  at the time if we would be able to keep the gap as we would add more
-  features to the linker.
-
-- July 2016: Started working on improving the linker script support.
-
-- December 2016: Succeeded to build the entire FreeBSD base system
-  including the kernel. We had widen the performance gap against the
-  GNU linkers.
