  @mainpage Exif and Iptc metadata manipulation library and tools v0.6.2

  @section overview Exiv2 Overview
 
  Exiv2 is a C++ library that provides
  - read and write access to the Exif and Iptc IIM metadata of an image 
    through %Exiv2 keys and standard C++ iterators 
  - Exif MakerNote support:
      - MakerNote tags can be accessed just like any other metadata
      - a sophisticated write algorithm avoids corrupting the MakerNote: 
         <BR>&nbsp;&nbsp;1) the MakerNote is not re-located if possible, and 
         <BR>&nbsp;&nbsp;2) MakerNote IFD offsets are re-calculated if the MakerNote
                            needs to be moved (for known IFD MakerNotes)
      - new camera make/model specific MakerNotes can be added to the library
        with minimum effort in OO-fashion (by subclassing MakerNote or IfdMakerNote)
  - set methods for Exif thumbnails (Jpeg only, Tiff thumbnails can be set from 
    individual tags)
  - extract and delete methods for Exif thumbnails (both, JPEG and TIFF thumbnails)
  - Doxygen API documentation
  - generic lower-level classes to access IFD (Image File Directory) data structures

  %Exiv2 is also a command line program to
  - print the Exif metadata of JPEG images (as summary info, interpreted values, or
    the plain data for each tag)
  - print the Iptc metadata of JPEG images
  - print the Jpeg comment of JPEG images
  - adjust the Exif timestamp (that's how it all started...)
  - rename Exif image files according to the Exif timestamp
  - extract Exif metadata, Iptc metadata and Jpeg comments from image files and 
    insert it again
  - extract the thumbnail image embedded in the Exif metadata
  - delete the thumbnail or the complete Exif metadata from an image
