----------------------------------------------------
 This program makes a little character spinner. 
 e.g. - \ | / - \ | / ...                       
 It is useful for keeping links alive, etc.     

 Usage: spinner [<delay_in_sec>]                
 The delay is the time between each tick of the 
 "spin". If no delay is provide a default is    
 used.                                          

 This is obviously a trivial prog. I found it   
 useful for ssh keepalives through firewalls    
 that timeout idle connections. Hopefully you   
 will too...                                    

 On un*x you can execute the ./Build shell script
 to compile spinner, or you can compile this with:                     
                                                
 gcc -O2 spinner.c -o spinner                   
                                                
 This will generate a binary called "spinner".  
 Try executing it with "./spinner 0" or just    
 plain "./spinner" for the default delay.       
 If you use this to keep alive a connection use 
 a delay of 2-30 secs. as not to waste          
 bandwidth.                                     
  
  *Windows users: The provided binary is a command
 line (DOS shell, Command Prompt) program. You
 execute it from the command line by typing the
 name of the program ("spinner") while in the
 same directory as the file. You may optionally 
 move it to a directory in your PATH. If you wish
 to use a spin delay other than 2 seconds you enter
 the delay in seconds as the second argument to the
 command. ("spinner 5" for 5 sec)
 

 Hopefully somebody will find this useful. I use it
 when connected to remote servers to keep the link
 from timing out when I am connected through a
 firewall that times out idle connections. It can
 also be used to keep remote X windows sessions open,
 etc.
