                        Announcing Frysk 0.2.1

Frysk is a debugging and monitoring framework being developed using
Java and C++.  It is aimed at providing developers and system
administrators with the ability to examine and analyze multi-host,
multi-process, and multi-threaded systems while they are running.

We, that is, Adam Jocksch, Alexandre Oliva, Andrew Cagney, Carlos
Eduardo Seo, Chris Moller, Diego Novillo, Elena Zannoni, Frank
Ch. Eigler, Igor Foox, Ivan Pantuyev, Jan Kratochvil, Jeff Johnston,

Henderson, Rick Moseley, Sami Wagiaalla, Stan Cox, Stepan Kasal, Tarun
Khanna, Teresa Thomas, Thomas Gerard, Tim Moore, Tom Tromey, Wu Zhou,
Yao Qi, Yong Zheng, and Zhao Shujing are pleased to announce our first
official release of Frysk, version 0.2.1.

This initial release includes:

-> command line utilities:

   fauxv - print the auxiliary vector (new)
   fcatch - catch and print the stack of a crashing process
   fcore - extract a core file from a running process (faster, more correct)
   fdebuginfo - list debug-info requirements of a process (new)
   fdebugrpm - install debug-info requirements of a process (new)
   ferror - catch and back-trace error calls (new)
   fexe - print the executable path
   fmaps - print the address map (new)
   fstack - print each thread's stack (supports in-line back-traces)
   fstep - single-step a process
   ftrace - trace a processes system and (new) library calls

   Known limitations: large resident set size; large executable size.

-> Prototype command line debugger: fhpd

   For single threaded programs, FHPD can: print the value, type, and
   location, and modify the value of, arbitrarily located variable
   (complex DWARF location expressions); correctly handle very-large
   integers (>64-bit) and large floats (80-bit); display in-line
   information in back-traces; control processes with the commands
   load, core, dump, run, step, break, go, detach, kill, list, focus.

   In addition to the command-line utility restrictions, the HPD has
   the following known limitations: disassembler missing; limited
   type-cast support in expressions; limited multi-thread support.

-> Prototype visual debugging and monitoring tool (frysk)

   Known limitations: work-flow limited to live processes (examining
   core files, or creating processes is possible but very

-> Prototype test-suite (funit)

   Known limitations: some test that are working in-tree fail when
