CINDA.
IAEA-NDS, 2009-03-27
--------------------
Introduction.
-------------
Algorithm of blocking was changed in order to be compatible with NEA-DB:
now if all information identifying Block is the same, new-Quantity is known 
and old-Quantity is different - lines have to be in one block. (According to
old definition: both Quantities must be the same for the lines to be in the
same Block.) Due to the new algorithm, some blocks from old version of CINDA
will be merged - those which have either the same authors or the same reference.
This is major difference between old and new CINDA. Second difference:
when blocks are merged, duplicating lines (having the same Comment, but 
different old-Quantities) will not be repeated in the database. Third 
difference: the lines automatically created on the basis of current EXFOR
(they have reader-code "X4") are deleted on the first stage after applying
the new algorithm of blocking for the backup dated 2006-06-22.
Automatic extension of CINDA was done only on the last stage (update5).

Sequence of actions.
--------------------
   ./cinda-00
	a) starting point: "bck-2006-06-22/*.c2k"
	b) merged lines, because of new algorithm: "merged-a*.log"
	c) duplications left (need manual corrections): "dup-a*.txt"
	d) new backup: "backup-2006-06-22-new/*.c2k"
   ./update0-x4del
	a) delete lines automatically created from EXFOR: "x4del_a*.exch0"
   ./update1	\
   ./update2	 \	manual input
   ./update3	 /	to CINDA by NEA and NDS
   ./update4	/
   ./update5   /
   ./update5after	backup of "manual CINDA"
   ./update6-x4auto	lines automaticaly generated from EXFOR as of 2009-03-23
   ./update6after	backup of "final CINDA"
