Installation Procedure:
  0.  Install the above dependencies using your package manager.
  1.  Download the tar file by clicking one of the above links.
  2.  Open a terminal window and enter the following commands:
  3.  $ chdir Downloads                    # go to the tar file
  4.  $ tar -xzf appname-xxx.tar.gz        # unpack the tar file
  5.  $ chdir appname                      # go to unpacked files
  6.  $ make                               # build program
  7.  $ sudo make install                  # install program

Missing dependencies will cause error messages in step 6. 
Install these using your package manager and repeat step 6.
 
Step 7 installs program files in the following locations:
   /usr/bin, /usr/share/appname, /usr/share/doc/appname

Uninstall appname:
  $ sudo rm -f /usr/bin/appname  
  $ sudo rm -R -f /usr/share/appname
  $ sudo rm -R -f /usr/share/doc/appname
  $ rm -R -f /home/<user>/.appname
