--------------------------
- Pending resolution of SOC SPR 2500 I have, as a workaround, patched SSC SPR 3223 by including defaults for all mandatory parameters.

Version 7.1.3 - 2004-01-13 (IMS SSC/LUX)
--------------------------
- Fixed SPR 3205 by left-justifying a string.

- Introduced some more messages.
- Documentation update.
- Can't reproduce SPR 3031.

--------------------------
- Fixed SPR 3183.

Version 7.1 - 2003-11-23 (IMS SSC/LUX)
--------------------------
- Removed old code.

Version 7.0 - 2003-11-10 (IMS SSC/LUX)
--------------------------

Version 6.4 - 2002-07-12 (IMS SSC/LUX)
--------------------------
- Added sas to DEPEND.

Version 6.3 - 2002-05-17 (IMS SSC/LUX)
--------------------------
- Uses param-2.0
- Slight doco fix.

Version 6.2.2 - 08 Mar 2002 (IMS SSC/LUX)
--------------------------
- Updated DEPEND (including ssclib -> 2.4).

Version 6.2.1 - 11 Feb 2002 (IMS SSC/LUX)
--------------------------
- Slight rearrangements to cope with corrections in ssclib (fixes to SPR 2744).
- Removed unecessary dependency on sla.

Version 6.2 - 24 Jan 2002 (IMS SSC/LUX)
--------------------------
- Changed the way SHAPE column entries in the region files are written, to eliminate spurious characters.
- Restored the evselect calls in the test harness.

Version 6.1 - 23 Jan 2002 (IMS SSC/LUX)
--------------------------
- Updated DEPEND and added evselect.
- Fixed test harness (but temporarily commented out evselect calls).
- Fixed variable decl., array bound bugs.

Version 6.0 - 17 Jan 2002 (IMS SSC/LUX)
--------------------------
- Changed the major version number because what started as a bug fixed ended up as a complete rearrangement.
- User now has choice between DETX/Y and X/Y systems (via param --outunit).
- Changed parameters --regionfile and --bkgregionfile to optional and gave them defaults.
- Choice 'tobkgfrac' added to param --radiusmode and param --bkgfraction added to handle this option.
- Param --eventfile changed to dataset type ('e') and renamed --eventset.
- SPRs 2385 and 2394 closed.
