I am trying to read from a text file using the following code:

        line = strip(file.readln());
        if (line[0] == '>') {         // line 10
            writeln(line[1..$]);
        }
        else {
            writeln(line);
        }
    }
}

and I get the following error AFTER the last line is processed:

core.exception.RangeError@readfile.d(10): Range violation
----------------
??:? _d_arrayboundsp [0x448efa]
??:? _Dmain [0x4459f7]

Any idea what I am doing wrong?  When processing the if 
statement or writing the slice, am I inadvertently trying to 
read a non-existent line in the file?

Thanks in advance
Samir

stripping the last line could result in an empty line if it just 
has strippable characters?
