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 1.3.0
=================================================
    Configuration
    -------------
    - None
    
    Features
    --------
    - Added support for nagg like (-l, --like) option. It packages file like
      the given example file. (AKC 2012/08/30)
    - Added support for nagg --version. (LK 2012/08/01)
      
    Bug Fixes
    ---------
    - The NPP product table had an incorrect granule duration for IICMO, nagg
      -h or --help printed incorrect granule durations for some of the GEO
      products, and 2 of the NPP products had incorrect GEO products listed.
      These errors have been corrected in this version. (LK 2012/08/01)

    Limits
    ------
    - See nagg.docx (html, pdf) in the same directory for proposed functionality.
    Current release has the following limitations: 
       * Like (--like) option retrieve two properties (number of granules and
         types contained) from the example file. Note that it does not
	 retrieve properties such as geolocation product used, packaged or
	 unpackaged, origin and domain. It also does not support geolocation
	 product only aggregation since it does not retrieve geolocation
	 product properties.
       * Environment variables or command line options for compliance 
         with file naming convention presume valid types and packaging as
	 defined in the "nagg.h" file.
       * 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.
