read_bytes 
NAME 
read_bytes()  -  reads  a contiguous series of bytes from a file into a
string
SYNOPSIS 
string read_bytes( string path, int start, int length );
DESCRIPTION 
This function reads 'length' bytes beginning at byte # 'start'  in  the
file  named  'path'.   The  bytes  are returned as a string.  Note that
(start + length) must  not  be  past  the  end  of  the  file  or  else

the entire file is returned.
