Version 3.3.0
	29-Apr-2009 Ilya Dricker (i.dricker@isti.com)
	*MODIFIED: processing of delays in FIR stages.
	      Now the following rules are applied for adding delays to the FIR
	      stages:
	      1) Calculation of the response for a symmetrical FIR filter ignores
	      the delay value in the RESP;
	      2) Calculation of the response for an asymmetrical FIR filter
		uses the "correction applied" field of the RESP by default and
		"estimated delay" field on user request (a user should use an
		option -use-estimated-delay to switch this option on).
	* ADDED: use CFLAGS environment variable as compiler options	
Version 3.2.40
	20-Jun-2008 Ilya Dricker (i.dricker@isti.com)
	* FIXED: bug in computation time limits
	25-Sep-2007 Ilya Dricker (i.dricker@isti.com)
	* REMOVED: 2 return statements in eversp which break LIB_MODE logic
Version 3.2.39
	12-Jul-2007 Ilya Dricker (i.dricker@isti.com)
	*REMOVED: -g -Wall hardcoded flags from configure.in. Made then configurable 
	   options;
Version 3.2.38
        04-Mar-2007 Ilya Dricker (i.dricker@isti.com)
        *ADDED: new configure option --enable-log-label
          When evalresp is configured with this option, most of log messages
          are being prepended by a label. A label consists of [Net.Sta.Loc.Chan].
        27-Feb-2007 Ilya Dricker (i.dricker@isti.com)
        * ADDED: Return (#ifdef LIB_MODE) if input file is not found
	01-Feb-2007 Ilya Dricker (i.dricker@isti.com)
	* FIXED: Bug pointed by <alessia@sismo.u-strasbg.fr> : use 
	  else if(!strcmp(argv[i], "-u")) instead of just if in evalresp.c:141
        08-Nov-2006 Ilya Dricker (i.dricker@isti.com)
        * Libtoolized evresp library: using libtool instead of ranlib.
	  Now a builder can create dynamic library, not only static
Version 3.2.37
	16-Oct-2006 Eric Thomas (e.thomas@isti.com)
	* Added two more 'free()' calls to "evresp.c" to fix memory leaks
          when program functions are used in external applications.
Version 3.2.36
	21-Aug-2006 Ilya Dricker (i.dricker@isti.com)
	* Modified to support Tesla ("T") units.
Version 3.2.35
	4-Apr-2006 Eric Thomas (e.thomas@isti.com)
	* Modified to support channel-IDs with location codes equal
          to an empty string.
Version 3.2.34
	28-Mar-2006 Eric Thomas (e.thomas@isti.com)
	* Added 'free()' calls to "evresp.c" to fix memory leaks when
          program functions used in external applications.
Version 3.2.33
	27-Mar-2006 Ilya Dricker (i.dricker@isti.com)
	* Added include_HEADERS target "evr_spline.h" to "Makefile.am".
	* Upgraded missing script.
Version 3.2.32
	13-Feb-2006 Eric Thomas (e.thomas@isti.com)
        * Moved 'use_delay()' function from 'evalresp.c' to 'evresp.c'.
        * Modified to close input file when a single response file is
          specified.
Version 3.2.31
	19-Jan-2006 Eric Thomas (e.thomas@isti.com)
        * Renamed 'regexp' functions to prevent name clashes with other
          libraries.
        * Restored 'depcomp' script in distribution.
Version 3.2.30
	3-Nov-2005 Eric Thomas (e.thomas@isti.com)
        * Modified to unwrap phase values before interpolation and re-wrap
          after (if needed).
	* Modified to detect when all requested interpolated frequencies
          are out of range.
Version 3.2.29
	21-Oct-2005 Eric Thomas (e.thomas@isti.com)
	* Implemented interpolation of amplitude/phase values from
	  responses containing List blockettes (55).
	* Modified message shown when List blockette encountered.
	* Modified so as not to require characters after 'units'
	  specifiers like "M" and "COUNTS".
	* Modified to handle case where file contains "B052F03 Location:"
	  and nothing after it on line.
	* Added warnings for unrecognized parameters.
	* Fixed issue where program would crash under Linux/UNIX
	  ("segmentation fault") if input response file contained
	  Windows-style "CR/LF" line ends.
Version 3.2.28
	2-Aug-2005 Eric Thomas (e.thomas@isti.com)
	* Modified to allow command-line parameters for frequency
	  values to be missing (default values used).
Version 3.2.27
	1-Mar-2005 Ilya Dricker(i.dricker@isti.com)
	* Added -add-delay command line option
Version 3.2.26
	20-Oct-2004 Ilya Dricker (i.dricker@isti.com)
	* Techical modifications for Mac OS X portability
Version 3.2.25
	20-Jul-2005 Ilya Dricker (i.dricker@isti.com)
	* Finally, we started ChangeLog
	* FIXED: Processing of B55 + GAIN stage is now allowed
	* ADDED: config.h to the source code and AM_CONFIG_HEADER to
            configure.in
