CoW was originally developed at the University of California, Davis
by Takashi Ishihara <ishihara@cs.ucdavis.edu> as part of his graduate

research on cooperative multithreading.  The project is now maintained
by Matt Roper <roper@cs.ucdavis.edu>.  Please send all bug reports and
feature requests to Matt.

Compile/Install:
./configure	# you must edit Mekefile to set appropreate /path/to/pth
make
make install

example of Makefile modification:
CFLAGS  = -I/home/ishihara/pkg/include
PTHDIR  = /home/ishihara/pkg/lib

I also modified pth lib a bit, but no time to find it out, so if you had

CoW uses a slightly modified version of GNU Pth as its threading
library.  A stripped down copy of Pth is included in the CoW
distribution and will be statically linked into the final executable;
it is no longer necessary to install and patch a separate copy of Pth.
The provided copy of Pth has been modified to include experimental
support for Linux 2.6's sys_epoll event notification mechanism.  This
is likely to be less stable than the traditional select()-based event
notification, but it should also provide higher performance.  To enable
the epoll-based event notification, pass the "--with-epoll" switch to
the configure program. 

any problem, please let me know, and i'll fix immediately.

Coding Style:
indent -bli0 +line-length80 *.c
(but not indent'ed all files) 

The following command line switches are recognized by CoW:
    -c <cfgfile>
        Specifies the name and location of the CoW configuration

        file.  By default, CoW will search for a configuration file
        at /etc/cow.conf, /usr/local/etc/cow.conf, and finally at
        ./cow.conf.  
    -d
        Tells CoW not to background itself; generally only used
        during debugging.
    -r <serverroot>
        Specifies the base document directory from which files
        will be served.  If this switch is present, it will override
        the value of ServerRoot in the configuration file.  If this
        switch is not present and ServerRoot is not set in the config
        file, the current directory will be the server root.
    -p <serverport>
        Specifies what TCP port the server should run on.  This switch
        overrides the ServerPort setting in the configuration file.
        If this switch is not present and no value is set for
        ServerPort in the configuration file, 8080 will be used.
    -f <numprocs>
        Tells CoW to fork off a total of <numprocs> processes.  By
        default CoW only uses a single process, but since operating systems
        generally impose a 1024 file descriptor per process limit,
        this option allows us to effectively multiply the number of
        file descriptors available to CoW (and thus increase the
        maximum possible concurrency).  Do not confuse this forking
        mechanism with Apache-style forking -- Apache uses one process
        per request, but each CoW process can handle about 1000 simultaneous
        requests.
    -b <backlog>
        This option is passed to the underlying listen() system call and
        controls the number of pending connections allowed.  You should
        generally leave this option at its default value.
    -v
        This switch enables some extra console output during startup.
        You probably won't need to use this unless your trying to
        debug CoW.

CoW is alpha, meaning it's experimental + under development. 
Suggestions are welcomed.
In the process of cleaning up the src, it seems that one or more feature

CoW is still in alpha, so there are probably bugs.  If you have any
questions, don't hesitate to send an email to roper@cs.ucdavis.edu.
Send bug reports to the same address. 

working before now seem to have troubles. I'll fix ASAP.
More info is available from http://wwwcsif.cs.ucdavis.edu/~ishihara/cow/ .
Current version may not work with non-pool version (defined in schedule.h) .
.. and I know src need to be re-organized + re-written  + clean-up more.
