============================================

1. Introduction
===============

This document describes the NPP Aggregation tool, nagg, and contains
information on platforms tested, changes since last release and any known
problems.

If you have any questions or comments, please send them to:
    help@hdfgroup.org


2. Platforms Tested
===================
Linux 2.6 32bit and 64bits with gcc 4.1.2 and icc 12.0.4


3. New features and bug fixes since Version 1.0.0
=================================================
    Configuration
    -------------
    - A bug that happened during build with icc compiler, has been fixed.
      (LRK 2012/2/25)
    
    Features
    --------
    - Implemented "-g no" option.  The no option directs nagg to aggregate or
      deaggregate product granules without finding Geolocation input granules
      and without writing any Geolocation output granules. (LRK 2012/03/07)
    - Added a new command option "-g" which controls the criterion for
      searching the Geolocation granules.  See command help page for details.
      "strict" and "yes" criterions are implemented. "no" will be implemented
      in the next version.  (AKC 2012/02/28)
    - Added the correct granule size (duration) for all products and expect
      to produce the same aggregations as DDS and CLASS, pending any revisions
      that may be made to the aggregation methodology. (AKC 2012/02/28) 

    Limits
    ------
    - See nagg.docx (html, pdf) in the same directory for proposed functionality.
    Current release has the following limitations: 
       * Environment variables or command line options for compliance 
         with file naming convention presume valid types and packaging as defined 
         in the "nagg.h" file.
       * Grouping by time rather than number of granules (-A flag) is not supported
         (e.g., 7 minute 59 second granules starting at a given time rather than just at 
         the earliest granule encountered.)
       * Warnings or failures if granule gaps exceed some threshold are not
         supported.
       * Compression on output is not supported.
       * Options to choose repair granule are not supported; for now, the one with the latest version is used.
       * Option to replace existing granule with repair granule is not
         supported.  
       * Restrictions on flags and input parameters:
            Directory input is not supported.
           -t - only one single type is supported.
           -l - not supported
           -A - not supported
           -S - not suported
           -d - not suported

      
4. Known problems
=================
    - Missing granules result in UNKNO geofiles.  JPSS-38
    - Duplicate granules cause production of extra output files.  JPSS-39
    - EndingDate value for fill granules is "N/A".  JPSS-40
