I don't just think it's OK to have a trivial driver, I think it is the goal. See for example pod2html. The one installed with my Perl is 144 lines. Of those, 137 are POD and 2 others are blank.

By carefully factoring code out of the script into modules, you allow other script and module authors to leverage your code. If you leave everything (or anything) in the script reuse becomes harder, especially if you don't use many subs.

I think of a the ideal script as a mapper between command line arguments and one or more modules (not that I always achieve the ideal).

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
