    <p>How can I check if a Perl module is part of the core - i.e. it is part of the standard installation?</p> <p>I'm looking for:</p> <ul> <li>a command-line command:</li> <li>a Perl subroutine/function to check within code</li> </ul> <p>Perhaps the question should be: How can I tell what modules were originally provided with the <em>specific</em> Perl installation on a machine? (Actually, it is now asked as <em><a href="https://stackoverflow.com/questions/2085516/how-can-i-tell-what-modules-were-originally-provided-with-the-specific-perl-insta">How can I tell what modules were originally provided with the specific Perl installation on a machine?</a></em>.)</p> <p>Given that there now appears to not to be an overall Perl standard installation, at least the answer to this new question will tell me what I originally had in the installation when it was first installed.</p> <p>With that knowledge and if I keep the original installer image/package OR know how to get the exact thing again online, then I have a repeatable Perl installation for several machines with the knowledge of what modules will be present and what modules will not. </p> <p>To clarify further: I am looking at what <em>came</em> with the installation originally, what modules were provided as part of that installation, and what was built-in. <em>NOT</em> what has been installed since then.</p> <p>And I want to be able to do this <em>on the machine that has the installation</em>. So for this I would be relying upon the installation to have a record in some form as to what it has originally.</p> <p>I asked spin-off question: <em><a href="https://stackoverflow.com/questions/2085516/how-can-i-tell-what-modules-were-originally-provided-with-the-specific-perl-insta">How can I tell what modules were originally provided with the specific Perl installation on a machine?</a></em> (How can I tell what modules were originally provided with the specific Perl installation on a machine?)</p>

    2. COIt doesn't matter what platform. What I'm looking for in this new question (under the heading 'update') is a general piece of code that I can use to run on a particular machine to determine what modules were originally part of the Perl installation on that particular machine. Regardless of whether it is Debian 4,5 or Ubuntu or Mandriva or whatever.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
