puf developement history
------------------------

1.1.0 ( 2006)
    - Made -i async when openend on FIFO or socket
    - Fixed CGI recursion without -ng & -xg
    - Added -nD*, -I*, -X*
    - Added pcre-based variants of -D*/-nD*/-I*/-X*

1.0.0 (16 Oct 2005)
    - Fixed command line parsing error that caused -d to be taken as -dc
    - -r[+[+]] doesn't imply -p any more, but it advances -p to -pr[+[+]]
    - The scope of URL-based switches can be limited with brackets now
    - The file supplied to -i is now interpreted as a generic command file
      with one command line switch (incl. argument) or URL per line
    - Dropped SPEC format - use -O and the new -xy/-xyy switches instead
    - $http_proxy is now obeyed if no proxies are specified with -y/-iy
    - Scope of -O switch unified with other URL-based switches
    - Made -O buffer output when dumping multiple sources to one target
    - Added support for "-O -"
    - Added -A, -R, -D, -Dl, -Dr, -xr, -xu, -xs, -xo and -xO switches
    - Removed -xe switch
    - -xE now enumerates per occurrence of -P
    - Vast performance improvements of large downloads
    - Automatically %-escape [invalid] spaces in URLs
    - Various bug fixes
    - Change of versioning scheme to something more reasonable

0.93.3 (20 May 2004)
    - Don't retry after HTTP errors 403 and 404. Added -xT switch to
      enforce the old behaviour (for some really broken servers)
    - Don't spawn a separate process for every DNS lookup, but use a
      pool of DNS helper processes instead
    - Added -xh and -dc switches
    - Fixed file corruption on CygWin

0.93.2a (1 Oct 2002)
    - Fixed build. obviously some automake 1.5 problem.
      A re-gen with automake 1.6 fixes the problem.

0.93.2 (23 May 2002)
    - Removed proxy duplicate detection (together with a bug in it) -
      I don't think it was useful at all

0.93.1 (10 May 2002)
    - Fixed format string vulnerability in error output
    - Refuse to compile on systems without snprintf
    - Fixed overflow resulting in bad bandwidth averages for _very_ big 
      downloads or very fast networks
    - Made most switches URL-based, i.e., the switch applies only the the URLs
      that follow it and can be turned off again for URLs listed later
    - -p switch renamed to -B (wget-like)
    - -ri switch replaced by -p, -pr, -pr+ & -pr++ (somewhat wget-like)
    - Added -xq switch

0.91beta3 (21 Jan 2001)

    - -xb switch to bind source ip

0.9beta6 (26 Oct 2000)
    - reduced the default for -ll to 10 - otherwise the common file 
      descriptor limit of 50 may be reached too fast

      very long header (e.g., an ultralarge cookie)

0.9beta5 (24 Oct 2000)
    - Bug fix: uninitialized variable caused files to be saved under weird

    - Oswald Buddenhagen took over the project
    - Nearly complete rewrite
