+A File Encryption Utility - VC++ 7.1 project Instructions
+
+1.	Unzip the enclosed files into a suitable VC++ project directory.
+2.	Obtain the bzip2 source code from http://sources.redhat.com/bzip2/
+	and unzip the files into the bzip2 sub-directory.
+3.	Compile the bzip2 project to give a static library
+4.	Compile the encfile project.
+5.	The executable encfile.exe is now ready for use:
+
+		enfile password filename
+	
+	If the filename does not have the extension 'enc', it is assumed to 
+	be a normal file that will then be encrypted to a file with the same
+	name but with an added extension 'enc'.
+	
+	If the filename has the extension 'enc' its is assumed to be an 
+	encrypted file that will be decrypted to a file with the same name
+	but without the 'enc' extension.
+
+The default HASH function is SHA1, which is set up by defining USE_SHA1 in
+compiling the project.  If USE_SHA256 is defined instead then SHA256 is used.
