	    -	first public release.

04/09/2001
        * 0.2.8:
	    -	rewrote command line parameters handling.
	    -	added a couple of output messages.

04/24/2001
	* 0.3.0:
	    -	added option to timestamp output
	    -	added option to print number of bytes transmitted

04/25/2001
	* 0.3.1:
	    -  fixed the infinite loop when looking for available pty bug
		(those typos will kill me one day :)

06/09/2001
	* 0.3.2:
	    -  added optional colors for terminal output.
	    -  fixed a bug with logfile name including '=' when
	       specified as `--log=<filename>`
	       
09/25/2001
	* 0.3.3:
	    -  fixed a bug with shell piping and output redirection
	       (`slsnif <parameters> | more` and Co. should work fine now).

10/21/2001
	* 0.3.4:
	    -  now compiles on a Sun SPARC Solaris 7 machine, thanks
	       to Heiko Nardmann (h.nardmann@secunet.de)

12/12/2001
	* 0.4.0:
	    -  added ability to lock the port ('-n' and '--nolock'
	       parameters).
	    -  added ability to use a real serial port instead of a
	       pty, thus enabling data logging between two ports.
	       ('-p' and '--port2' parameters).
	    -  now port parameters (termios structures) of both ports
	       are syncronized as soon as first chunk of data appears
	       on a host (pty) side, so setting baudrate is necessary
	       only if controlling software doesn't set it.
	    -  rewrote timestamping code to give more precise output
	       if ftime() function is present. New code is a bit slower
	       than the old one, if that causes problems (unlikely) one
	       can always force slsnif to use old code by changing line
	           #define HAVE_SYS_TIMEB_H  1
	       to
	           #undef HAVE_SYS_TIMEB_H
	       in config.h file before compilation.
	    -  added ability to read certain parameters from rc-file,
	       see README and man page for details on syntax.
	       An example of such file (slsnifrc-example) is included
	       in the distribution.
	    -  fixed some minor bugs.
