      patterns form matching and -tag_rpattern option uses regular expresion
      patterns.

version 0.9pl30a
----------------

<CLI> Added new mode MIRROR that is supposed to get an exact copy of the remote
      server. Mode SYNC tries to get as many files from the remote site as 
      possible while mode MIRROR in case of http mirroring will not try to
      load files that are no longer linked to (as mode SYNC tries to do).

<CLI> Mode MIRROR uses the same file names as the remote site. No quoting of
      possible unsafe characters in file names is done like for mode SYNC. 

<CLI> Now the exit code of pavuk indicates if an exact
      copy of the remote server could be made. The original mode SYNC considered
      skipping of downloads (e.g. because the remote file is already present on
      the local system) to be an ERROR!

      Now exit code 0 is used to indicate an exact copy and no download errors.

<CLI> New option -active_ftp_port_range permits to specify the ports used for
      active ftp. This permits easier firewall configuration since the range
      of ports can be restricted.

      Pavuk will randomly choose a number from within the specified
      range until an open port is found. Should no open ports be found
      within the given range, pavuk will default to a normal
      kernel-assigned port, and a message (debug level net) is output.

      The port range selected must be in the non-privileged range
      (eg. greater than or equal to 1024); it is STRONGLY RECOMMENDED that
      the chosen range be large enough to handle many simultaneous
      active connections (for example, 49152-65534, the IANA-registered
      ephemeral port range).

<CLI> Bug fixed that caused system chrash in case of some relative links
      that specified no filename (e.g. ''). See htmlparse.c
      for details (search for "'#'").

<CLI> When parsing the FTP listing pavuk now also tries to evaluate the 
      modification time of the listed files. This only works if -ftplist
      is specified (possibly also requiring -ftp_list_options -a) and
      at the moment only for UNIX file system listings.

<CLI> Originally pavuk in ftp mirror mode (e.g. SYN, MIRROR) sent the
      following commands to the remote server for every file: "TYPE I" 
      (binary mode) and then got remote file size and remote modification time.
      Now the system uses the remote file size and remote modification time
      if this was already determined when listing the remote directory.
      See above point.

      "TYPE I" is now only sent if a file (or part of) is downloaded.

      These changes reduce the amount of sent ftp commands and thus fasten 
      comparisons of remote file system and local file system.

      Note that the file system listing usually has lower time precision than
      "MDTM". This means that the local file modification time might be 
      different than on the remote system.

      Use option -always_mdtm if you need the same modification time as the
      remote file; see below.

<CLI> New option -always_mdtm can be used to assure that pavuk always uses 
      "MDTM" to determine the file modification time and never uses cached times
      determined when listing the remote files.

<CLI> New option -remove_before_store/-noremove_before_store can be used to
      unlink files before new content is stored. This is helpful if the
      local files are hardlinked to some other directory and after mirroring the
      hardlinks are checked. All "broken" hardlinks indicate a file update.

<CLI> If remote file modification times are "in the future" (e.g. if the remote
      server's clock is inaccurate), then pavuk would not download files
      silently assuming that they are not yet expired. 
      (It only loaded files older than a specified number of days. If
      this number is not specified, the value 0 is used which means: do not
      load files newer than the current time; current time == current time of
      pavuk).

      Now such "No transfer - file not expired" is only done if an expire 
      time (option -ddays) is specified (i.e. value != 0).

<CLI> Fixed a bug that crashed pavuk when doing multi threaded downloads.

<CLI> The -max_time timeout is now also assured with alarm(). If pavuk fails
      to abort one minute after the given timeout, then alarm() will terminate
      it.

version 0.9pl30b
----------------
<CLI> added new option -referer and -noreferer to enable and disable the
      transfer of HTTP referer field.

version 0.9.32
----------------
<GUI> GTK2 compiles, still some problems.
<CLI> read support for KDE2 cookie file (~/.kde/share/apps/kcookiejar/cookies)
