Good, better, best!

I released a new distribution, Script::Singleton that ensures only a single instance of a script can run at any time. No methods or flags to use, you simply:

use Script::Singleton 'LOCK';
[download]

That's it! LOCK is the glue/key that identifies the shared memory segment. As with my last update, send in a true value to get a warning if a second instance of a script tries to run but has to exit:

use Script::Singleton 'LOCK', 1;
[download]

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 or How to display code and escape characters are good places to start.
