-----------------------------------------------------------------------------

The following are explanations of changes in the FGETS model system since the
publication of the user's manual file for version 3.0.14.  A brief
explanation and/or example may be given for a selected change/enhancement. 

-----------------------------------------------------------------------------

Changes
~~~~~~~
FGETS version 3.0.18
 - allows "cfish" as a diet item (food web mode)
 - allows "length" as an age-class diet item (food web mode)
 - provides more robust error checking
 - allows an input file name argument on the (DOS) command line, e.g.,
   c:\> fgets atest.in
 - provides more flexibility in the bounds of the (age | weight | length)-
   classes (diet command)

For FGETS version 3.0.18, if the integration method generates an incorrect
iterate, FGETS will halt.

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