13 July 2001:

-- added the "checkoverlap" command to ptraj.
   checkoverlap [mask] [min <value>] [max <value>] [noimage] 
   This will look through the list of atoms to look for atoms that
   have distances less than the specified minimum value (0.95) or
   greater than the maximum value (if specified).  You can turn off
   imaging with the noimage keyword

-- minor fixes in printing and fixed some memory leaks


7  November 2000:

-- fixed problem with "average" command and dumping of coordinates.
   When only a subset of the atoms were selected the wrong coordinates
   were being dumped unless the selection was sequential starting from
   the first atom.


31 October 2000:

-- added a command to rdparm to "printdelphicharge", i.e. a file of
   charges for the current parmtop that is in the format required by
   the Delphi program to assign charges.

-- fixed up the printing of hydrogen bond information; modified the
   h-bond command to not include "self" (within residue) h-bonds
   unless requested.

-- removed references to <strings.h> and replaced with <string.h>


7  September 2000:

-- turned off the automatic imaging of distances if no box angles
   are specified

-- fixed the handing of .gz and .Z files; allows the creation of
   compressed output trajectories on the fly (via the specification of
   .gz or .Z in the trajout filename)

-- fixed the semantics of "go"

-- fixed a bad memory problem when reading CHARMM trajectories

-- fixed the image familiar command to work properly.
