Gnuscope installation instructions.

• Download current source code (gnuscope.tar.gz) and place in directory to be unpacked.
• Unpack using:
  tar -xzvf gnuscope.tar.gz
  This will create a subdirectory named gnuscope, containing all the gnuscope files
• Change directories to gnuscope/src (cd gnuscope/src) and type "make".  This will compile and link gnuscope, with the executable (gnuscope) being placed in the directory above the current directory.
  
• Copy this executable to where it will be used.  Frequently /usr/local/bin, or ~/bin (the user's bin directory).  Literally: 
  cp ../gnuscope ~/bin
• Unless there is a peculiar path problem, typing gnuscope at the commandline should start the program.  If there is some question as to which program is actually being run, type "which gnuscope".
