title: Does the otherlibdirs Configure option rewrite or just modify @INC?
body: <p>I'm a perl noob and I have a very basic question regarding the <code>@INC</code> post: <a href="https://stackoverflow.com/questions/2526804/how-is-perls-inc-constructed-aka-what-are-all-the-ways-of-affecting-where-pe">How is Perl&#39;s @INC constructed? (aka What are all the ways of affecting where Perl modules are searched for?)</a></p>
  
  <p>Does the "otherlibdirs" Configure option completely rewrite the directories that are part of <code>@INC</code>, or merely add another directory? It's not clear to me from that answer what it does, and I don't want to screw up the whole <code>@INC</code> path.</p>
  
  <p>Thanks!</p>
