=head1 Environment Variable
 
 This software uses the flock function for exclusive control. The execution of the
 program is blocked until it becomes possible to read or write the file.
 You can have it not block in the flock function by defining environment variable
 CHAR_NONBLOCK.
  
 Example:
  
   SET CHAR_NONBLOCK=1
  
 (The value '1' doesn't have the meaning)
