+=head2 Extensions
+
+By default, Configure will offer to build every extension which
+appears to be supported.  For example, Configure will offer to build
+GDBM_File only if it is able to find the gdbm library.  (See examples
+below.)  DynaLoader and Fcntl are always built by default.  Configure
+does not contain code to test for POSIX compliance, so POSIX is always
+built by default as well.  If you wish to skip POSIX, you can set the
+Configure variable useposix=false either in a hint file or from the
+Configure command line.  Similarly, the Safe extension is always built
+by default, but you can skip it by setting the Configure variable
+usesafe=false either in a hint file for from the command line.
+
+In summary, here are the Configure command-line variables you can set
+to turn off each extension:
+
+    DB_File		i_db
+    DynaLoader		(Must always be included)
+    Fcntl		(Always included by default)
+    GDBM_File		i_gdbm
+    NDBM_File		i_ndbm
+    ODBM_File		i_dbm
+    POSIX		useposix
+    SDBM_File		(Always included by default)
+    Safe		usesafe
+    Socket		d_socket
+
+Thus to skip the NDBM_File extension, you can use
+
+	sh Configure -Ui_ndbm
+
+Again, this is taken care of automatically if you don't have the ndbm
+library.
+
+Of course, you may always run Configure interactively and select only
+the Extensions you want.
+
+Finally, if you have dynamic loading (most modern Unix systems do)
+remember that these extensions do not increase the size of your perl
+executable, nor do they impact start-up time, so you probably might as
+well build all the ones that will work on your system.
