.SH DESCRIPTION
.B ldconfig 
creates the necessary links and cache to the most recent shared libraries 
found in the directories specified on the command line, in the file 
\fI/etc/ld.so.conf\fR, and in the default trusted directories (\fI/lib\fR and 
\fI/usr/lib\fR).  The cache is used by the run-time linker.
.B ldconfig
checks the header and file names of the libraries it encounters when 
determining which versions should have their links updated.

.B Note:
Some features may not exist depending on how uClibc was built
