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.
