Daniel Barlow:
- He made SBCL play nicely with ILISP. He figured out how to get the
- CMU CL dynamic object file loading code to work under SBCL. He
- ported CMU CL's support for Alpha and PPC CPUs to SBCL, and then
- continued to improve the ports. He wrote code (e.g. grovel_headers.c
- and stat_wrapper stuff) to handle machine-dependence and
- OS-dependence automatically, reducing the amount of hand-tweaking
- required to keep ports synchronized. He's also provided support
- for SBCL (as well as for free Common Lisp in general) through
- his CLiki website.
+ His contributions have included support for shared object loading
+ (from CMUCL), the Cheney GC for non-x86 ports (from CMUCL), Alpha
+ and PPC ports (from CMUCL), control stack exhaustion checking (new),
+ native threads support for x86 Linux (new), and the initial x86-64
+ backend (new). He also refactored the garbage collectors for
+ understandability, wrote code (e.g. grovel-headers.c and
+ stat_wrapper stuff) to find machine-dependent and OS-dependent
+ constants automatically, and was original author of the asdf,
+ asdf-install, sb-bsd-sockets, sb-executable, sb-grovel and sb-posix
+ contrib packages.

Alexey Dejneka:
- He has fixed many, many bugs. There's no single summary theme, but
- he's fixed about a dozen different bugs in LOOP alone, and more
- in the compiler itself. It appears that a lot of his fixes there
- and elsewhere reflect systematic public-spiritedness, fixing bugs
- as they show up in sbcl-devel or as archived in the BUGS file.

+
+Paul Dietz:
+ He is in the process of writing a comprehensive test suite

+ caught an old deep problem in the implementation of the stack
+ analysis phase in the compiler.

William ("Bill") Newman:
He continued to maintain SBCL after the fork, increasing ANSI
