 Installation of fotoxx from source tarball
 
 Building fotoxx requires the following packages:  
    g++                      Gnu C++ compiler and linker 
    libgtk-3-dev             GTK3 graphics library (GUI base)
    libtiff-*-dev            tiff-8/16 image files
    libpng-*-dev             png-8/16 image files
    liblcms-*-dev            color spaces (sRGB/Adobe-RGB)
    libchamplain-gtk-*-dev   geomapping library
    libraw                   RAW file conversion library

 At run time the following packages are also needed:
    exiftool           read/write metadata (EXIF etc.) 
    xdg-utils          LSB standard Linux utilities
    binutils           GNU binary utilities
 
 The above are recent Debian names. Package naming is chaotic, 
 so you may have to to hunt down the names for other distros.
 
 Build and install fotoxx as follows:
    1. Download the tar file (fotoxx-N.N.tar.gz) to Desktop 
    2. Open a terminal window 
    3. $ cd Desktop                      # go to Desktop 
    4. $ tar -xzf fotoxx-N.N.tar.gz      # unpack to ./fotoxx 
    5. $ cd fotoxx                       # go there 
    6. $ make                            # build program 
    7. $ sudo make install               # install program
   
 Missing dependencies will cause error messages in step 6. 
 Install these from your repository and repeat step 6. 
  
 Step 7 moves all files to the following locations:
    /usr/bin/fotoxx             binary executable 
    /usr/share/fotoxx/          icons, translations ...
    /usr/share/doc/fotoxx/      README, man page ...
 
 Please review the user guide (Help menu) before trying fotoxx.
 
 NOTE: The optional fotoxx-maps package should be installed 
 only after fotoxx is installed.
 
 NOTES FOR PACKAGE BUILDERS:
 If $PREFIX is defined, files go there instead of /usr. 
 If $DESTDIR is also defined, files go to $DESTDIR$PREFIX. 
 Do not move any files into a separate "documentation" or 
 "data" package. This would make Fotoxx unusable.
