Diagnostics

• This is a nice way to add debugging messages, too:

        sub debug {}
        ...

        debug "\ttrying file $filenm\n";
        ...

• When you want to enable debugging, change sub debug to:

        sub debug { print @_ }

• Or change it permanently to:

        sub debug { print @_ if $ENV{JSJ_DEBUG} }

• My next book will be about debugging techniques
