Version 4.4
-----------
o handling of multiple TITLE (_struct.title) lines through the COM_TITLE
COMMON defined in the sfch_comt.fh INCLUDE file

o correction of SLIM when very small

o extraction of CR_NREF_REP - reported number of reflexions - from coordinate
files, passing it through CRDPDB_3 COMMON block; this is the one that is
printed in the Refinement Panel

o handling of PATH to `library' files through the sfch_path.fh INCLUDE file

o AD-HOC extraction of title associated to _struct.title in the CIF reading
procedure

o improved extraction of data from REMARK 3 records

o printing of version number at bottom of each PostScript page

Version 4.4.5
-------------
o Only read from PDB file the "RESOLUTION RANGE" record corresponding to
the used data (not the "DATA COLLECTION" one, if exists).

o In the "Local estimation" pages of the PostScript output, mark the "Side
chain or base" data of "Shift", "Density correlation", "Density index", and
"B-factor" corresponding to GLY with a triangle, because N.A., Not Applicable.

o Give the grey scale code for the outlying values of "Density correlation",
"Density index", and "B-factor" in the "Local estimation" pages of the
PostScript output.


Version 4.5.0
-------------

o Implement the generation of an HTML output, including the creation
of a set of PostScript files for the different plots - these PS files
must be processed by an external application (e.g. ImageMagick) to
produce JPEG files, that are referenced in the HTML pages.  For the
Local Estimation plots, his has been achieved by subdividing the
original task of BYRESPLOT subroutine into different routines -
RIGHTSIDE, LEFTSIDE, RESIDUEBARS.

o The production of the HTML related files is controled by an environment
variable, SFCHECKHTML: if not set the files are not produced.

Version 4.5.1
-------------

o In routine CHECKGRG, CONNECT is no more ceiled at 1.0 before writing in
the .dst file. The ceiling is performed by the graph routine.

o Local estimator value that could not be calculated for some residues, e.g.
when the OCCUPANCY is 0.0, are marked with -9.0. When that value is detected
by the graph routine no bar is plotted.

o Density Index (Backbone and Side Chain) and Connect use -9.0 (instead of
-1.0) to mark N.A. values

o The sfcheck.res file is no more deleted at the end of the run.

o The module sfplot has been implemented in sfch_graph.f. It is a standalone
graphic module to generate the PostScript (and possibly HTML) files from the
results (in sfcheck.res and sfcheck.dst files) of SFCHECK.
