Quick install info:

Create a temporary directory to experiment in, e.g:

  mkdir -p ~/src/i2c-tmp ; cd ~/src/i2c-tmp

Fetch and unpack the i2c code:

  wget -O i2c.zip https://gtoal.com/history.dcs.ed.ac.uk/archive/languages/imp77-tmp/gtoal/i2c.zip
  unzip -o i2c.zip

       This code *temporarily* uses my release of "ecce" for some housekeeping chores.  It is not
       installed automatically (mainly because our testers may have their own - possibly slightly
       different - copy of ecce already installed.)  It can be compiled as follows:

         wget -O ecce.c http://ecce.sourceforge.net/ecce.c
         gcc -g -o ecce8 ecce.c
      
       - and then put it somewhere in your path, such as /usr/local/bin/ecce8
       
       Note: ecce8 is 8-bit clean but without UTF8 support.  If you want to edit UTF8 files
             with ecce, add a second copy, compiled with: gcc -g -DWANT_UTF8 -o ecce ecce.c

Now check the INSTALL.sh script, which will create some symbolic links in /usr/local to files
in this current (i2c-tmp) directory, and when you're happy that this is OK on your system, type:

  sudo ./INSTALL.sh

Read the README-I2C-MANUAL.txt file before you use the compiler.  This is *PRE-RELEASE* and
there are lots of caveats.
