* Appending cronjob output to a file

Output of a cronjob can be captured and appended to a disk file,
instead of sending it via email or logging it using syslog.  This is
controlled by the _MICRON_OUTFILE (global) and _JOB_OUTFILE (per-job)
built-in variables.

* New option -P FILE

Writes PID of the running process to FILE.  The file will be removed
when the program terminates.

* Option -v replaces -o

To set initial value of a built-in variable, use the "-v NAME=VALUE"
option.

* The -V option

To obtain the micrond version, use the -V option.

* Bugfixes

** Fix allocation of environment and built-in variables defined in crontabs.
	  

* Syslog support

New option '-S FACILITY' switches diagnostic output to the given
syslog facility.

	  

* Fix invalid memory addressing in remopt command

* Fix building with flex >= 2.6.1 (EOF check)
	  

* Handling of control characters in syslog messages

If the message text contains ASCII control characters (ASCII 0 to 31),
these are replaced with their "caret notation", i.e. a caret
character followed by the character value XORed with 0100.  Thus,
horizontal tabulation (ASCII 9) becomes ^I, carriage return
(ASCII 13) becomes ^M, etc.  By default the newline character is
exempt from this translation.  Instead, it is substituted with
horizontal space (ASCII 32).

The "-Wcontrol_chars=MODE" option can be used to alter this
processing. Possible values for MODE are:

 caret
    Replace all control characters with their caret notation.  The newline
    character is represented as ^J.

 caretnl
    The default algorithm as described above.

 octal
    Replace control characters with their octal representation.

 raw
    Reproduce control characters verbatim.

* New option -s: set input buffer size

The -s option changes the default input buffer size.  Its argument is
the desired size in bytes.  For UDP input, values of up to 4096 are
allowed.  The default is 1024.

* New output channel: pri:///DIR

  Distributes messages to two disk files located in directory DIR.
  The name of the file to write to is selected depending on the message
  severity.  Messages with severity greater than LOG_ERR are directed
  to file "1" ("out" file), messages with severity less than or equal
  to LOG_ERR are directed to file "2" ("err" file).

  This channel understands the following parameters:

    severity=SEVERITY
       Gives name of the delimiter severity.  Messages with severity
       less than or equal to that value will be directed to "err" file.
       (DIR/2, by default).

    errfile=NAME
       Sets the name of the "err" file.

    outfile=NAME
       Sets the name of the "out" file.

    prio=none|keep|decode
       Controls whether and how the message priority is reflected on
       the output.  See the channel "file:" for details.

  Default settings correspond to:

      -Wseverity=err -Werrfile=2 -Woutfile=1 -Wprio=none
	  

* New configuration statement: sentinel

The "sentinel" statement declares the name of a file which, when
present in the destination directory, informs vcsync that this
directory is exempt from the normal synchronization process.  The
presense of the sentinel file is an indication that the destination
directory is updated by other means.
