How to Install Euphoria on Linux or FreeBSD
 -------------------------------------------
 
 Now that you've run tar to create the euphoria directory,
 you need to: 
    
    1. add euphoria/bin to your PATH
    
    2. create an environment variable: EUDIR
    
 To view the hidden files in your home directory, type: 
       
   ls -a
 
 One or more of these files is executed when you log in.
 For instance, if you have a hidden profile file such as 
 ".bash_profile", you can edit the line: 
 
   PATH=...  
 
 and add euphoria/bin to it.
 
 For example, a user called rob might do the following:

   PATH=/home/rob/euphoria/bin:$PATH

 You must also add a line for the variable EUDIR such as:

   EUDIR=/home/rob/euphoria

 And remember to export these variables, by adding this line:
 
   export PATH EUDIR

 euphoria/bin doesn't have to be first on your PATH, but if it isn't 
 you'll have to rename the "ed" shell script in euphoria/bin, and perhaps a 
 few others.

 Alternatively, system administrators can put EUDIR and the PATH change 
 into a global file, such as /etc/profile, so many users will be able 
 to access the Euphoria interpreter.
