+<para>
+ldconfig creates the necessary links and cache (for use by the run-time
+linker, ld.so) to the most recent shared libraries found in the directories
+specified on the command line, in the file /etc/ld.so.conf, and in the trusted
+directories (/usr/lib and /lib). ldconfig checks the header and file names
+of the libraries it encounters when determining which versions should
+have their links updated.
