+ He fixed many, many bugs on various themes, and has done a
+ tremendous amount of work on the compiler in particular, fixing
+ bugs and refactoring.
+
+Paul Dietz:
+ He is in the process of writing a comprehensive test suite
+ for the requirements of the ANSI Common Lisp standard. Already, at
+ the halfway stage, it has caught hundreds of bugs in SBCL, and
+ provided simple test cases for them. His random crash tester has
+ caught an old deep problem in the implementation of the stack
+ analysis phase in the compiler.
+
+Brian Downing:
+ He fixed the linker problems for building SBCL on Mac OS X. He
+ found and fixed the cause of backtraces failing for undefined
+ functions and assembly routines. He wrote the core of SBCL's
+ alternative interpreter-based EVAL.
+
+Miles Egan:
+ He creates binary packages of SBCL releases for Red Hat and other
+ (which?) platforms.
+
+Helmut Eller:
+ A lot of the code in the SB-INTROSPECT and SB-COVER contrib modules
+ was originally written by him for Slime/Swank.
+
+Lutz Euler:
+ He made a large number of improvements to the x86-64 disassembler.
+
+Andreas Fuchs:
+ He provides infrastructure for monitoring build and performance
+ regressions of SBCL. He assisted with the integration of the
+ Unicode work.
+
+Stephan Frank:
+ He contributed the SB-GMP contrib to exploit libgmp in bignum and
+ ratio arithmetic.
+
+Nathan Froyd:
+ He has fixed various bugs, and also done a lot of internal
+ cleanup, not visible at the user level but important for
+ maintenance. (E.g. converting the PCL code to use LOOP instead
+ of the old weird pre-ANSI ITERATE macro so that the code can be
+ read without being an expert in ancient languages and so that we
+ can delete a thousand lines of implement-ITERATE macrology from
+ the codebase.)
+
+Bruno Haible:
+ He devised an accurate continued-fraction-based implementation of
+ RATIONALIZE, replacing a less-accurate version inherited from
+ primordial CMUCL.
+
+Cyrus Harmon:
+ He fixed many PPC FFI and callback bugs. He ported Raymond Toy's
+ work on the generational garbage collector for PPC to Linux, finding
+ and fixing other SBCL bugs in the process.
+
+Matthias Hoelzl:
+ He reported and fixed COMPILE's misbehavior on macros.
+
+Daisuke Homma:
+ He added support for SunOS on x86 processors.
+
+ITA Software:
+ They hired Juho Snellman as a consultant to work on improvements to
+ SBCL, to be released into the public domain. The work they've funded
+ includes faster compilation, various improvements to the statistical
+ profiler, the SB-COVER code coverage tool, the interpreter-based
+ evaluator and the IR2-based single-stepper.
+
+Espen S Johnsen:
+ He provided an ANSI-compliant version of CHANGE-CLASS for PCL.
+
+Teemu Kalvas:
+ He worked on Unicode support for SBCL, including parsing the Unicode
+ character database, restoring the FAST-READ-CHAR optimization and
+ developing external format support.
+
+Dmitry Kalyanov:
+ His work was crucial in bringing the Windows backend forward; he
+ implemented pthreads and ported SB-THREAD to this platform.
+
+Yaroslav Kavenchuk:
+ He implemented several missing features and fixed many bugs in
+ the win32 port. He also worked on external-format support for
+ SB-ALIEN.
+
+Anton Kovalenko:
+ He introduced a safepoint-based stop-the-world protocol and greatly
+ contributed to features and bugfixes related to the Windows port.
+
+Richard M Kreyter:
+ He added documentation support for CLOS slot readers and writers,
+ provided several SB-POSIX and NetBSD patches, and cleaned up
+ several of the filesystem/pathname interfaces.
+
+Frederik Kuivinen:
+ He showed how to implement the DEBUG-RETURN functionality.
+
+Arthur Lemmens:
+ He found and fixed a number of SBCL bugs while partially porting
+ SBCL to bootstrap under Lispworks for Windows.
+
+David Lichteblau:
+ He repeatedly failed to update his entry in this file.
