• The usual header:

        #!/usr/bin/perl
        require 'getopts.pl';
        &Getopts('vi:');

        $SUFFIX = $opt_i;
        $CHANGED=0;

• $SUFFIX is another one of those features I implemented and then forgot

• With -i.foo the modified version of file x is written to x.foo

• Otherwise, it is modified in place

• We will see the code with the $SUFFIX stuff stripped out

• -v is a verbose reporting mode; I'll leave that out too
