Corrections and Changes Between Versions 2.00 and 3.0.14:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1)   Revised, updated, and/or added the following documents as per CEAM
     distribution standards:  READ.ME, UPDATE.TXT, RELEASE.TXT.

2)   Implemented CEAM standard installation INSTALIT/MediaBuilder code and
     logic.  Compressed, self-extracting, interactive installation program
     with on-line, context sensitive help.  Created external diskette labels
     as per CEAM SDLCM.

3)   Replaced FGETS executable task image file (XFGETSX.EXE) with 32-bit,
     protected mode file built with Lahey FORTRAN, F77L-EM/32 version 5.01
     and Phar Lap 386LINK version 4.1L (CEAM standard FORTRAN distribution
     tools).  DOS extender is bound into application EXE file with automatic
     virtual memory management; distributed royalty free.  No overlay
     structure--linked as flat memory model.  EXE file now requires 386/486
     based system with co-processor.

Corrections and Changes Between Versions 3.0.14 and 3.0.18:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1)   Updated and modified files RELEASE.TXT, UPDATE.TXT, and READ.ME files.

2)   Composed new INSTALIT/MediaBuilder code and logic.  Upgraded INSTALIT/
     MediaBuilder product version description and INF script files from
     version 3.19c to version 5.03d.  Implemented numerous code changes to
     correct minor problems and add features/enhancements.

3)   Recompiled and relinked FGETS model using Lahey FORTRAN 32-bit,
     protected mode compiler, Phar-lap linker, and Spindrift libraries.

4)   Replaced compile and link DOS batch command files with a single Lahey
     make file.

5)   Included new executable task image file (*.EXE) and all updated run time
     support programs and files to include FORTRAN source code for the
     FGETS model system version 3.0.18.

6)   Implemented numerous FORTRAN source code changes to correct minor
     problems that occured during program and/or model execution and add new
     features/enhancements to include:

     - allow "cfish" as a diet item (food web mode)
     - allow "length" as an age-class diet item (food web mode)
     - provide more robust error checking
     - allow an input file name argument on the (DOS) command line, e.g.,
       c:\> fgets atest.in
     - provide more flexibility in the bounds of the (age | weight | length)-
       classes (diet command)
     - if the integration method generates an incorrect iterate, FGETS will
       halt.

     For further information, refer to the user's manual file, USERSMAN.DOC.

7)   Included lastest version of user's manual as a WordPerfect document
     file.
