NAME

       update-nut - create or upgrade NUT database

SYNOPSIS

       update-nut

DESCRIPTION

       Download    the    full    ascii    version    of    the   USDA   Nutrient   Database,   available   from
       http://www.ars.usda.gov/nutrientdata or from http://nut.sourceforge.net, and unzip it in some directory.

       Then, run "update-nut" to create or upgrade the NUT code in the SQLite database that runs the application
       in the same directory as the USDA Nutrient Database.  If upgrading, you have to be in the same  directory
       as the "nut.db" file.  After this step, "update-nut" is not required for anything.  Updating the NUT code
       with  "update-nut"  is  independent of updating the USDA database, although it is certainly possible that
       the USDA could change the format of their tables, so that  a  later  version  of  "update-nut"  would  be
       required  in  order  to  read their tables or display new nutrients.  The main idea is that your personal
       data is permanent, even though the application code and USDA tables can change as necessary.
