bug email address.</para></sect4>

<sect4><title>iconv</title>
<para>iconv performs character set conversion.</para></sect4>

<sect4><title>iconvconfig</title>
<para>iconvconfig creates fastloading iconv module 
configuration file.</para></sect4>

<sect4><title>ldconfig</title>
<para>ldconfig configures the dynamic linker run time bindings.</para></sect4>

<sect4><title>ldd</title>
<para>ldd prints the shared libraries required by each program or shared
library specified on the command line.</para></sect4>

<sect4><title>lddlibc4</title>
<para>No description is currently available.</para></sect4>

<sect4><title>locale</title>
<para>locale is a Perl program which tells the compiler to enable
(or disable) the use of POSIX locales for built-in operations.</para></sect4>

<sect4><title>localedef</title>
<para>localedef compiles locale specifications.</para></sect4>

<sect4><title>mtrace</title>
<para>mtrace prints the multicast path from a source to a receiver (an IP
trace query).</para></sect4>

<sect4><title>nscd</title>
<para>nscd is a daemon that provides a cache for the most common name
service requests.</para></sect4>

<sect4><title>nscd_nischeck</title>
<para>nscd_nischeck checks whether or not secure mode is necessary for
NIS+ lookup.</para></sect4>

<sect4><title>pcprofiledump</title>
<para>pcprofiledump dumps information generated by 
PC profiling.</para></sect4>

<sect4><title>pt_chown</title>
<para>pt_chown sets the owner, group and access permission of the
slave pseudo terminal corresponding to the master pseudo terminal passed 
on file descriptor `3'.  This is the helper program for the `grantpt' 
function.  It is not intended to be run directly from the command
line.</para></sect4>

<sect4><title>rpcgen</title>
<para>rpcgen generates C code to implement the RPC protocol.</para></sect4>

<sect4><title>rpcinfo</title>
<para>rpcinfo makes an RPC call to an RPC server.</para></sect4>

<sect4><title>sln</title>
<para>sln symbolically links dest to source.  It is statically linked,
needing no dynamic linking at all.  Thus sln is useful to make symbolic 
links to dynamic libraries if the dynamic linking system for some reason 
is nonfunctional.</para></sect4>

<sect4><title>sprof</title>
<para>sprof reads and displays shared object profiling data.</para></sect4>

<sect4><title>tzselect</title>
<para>tzselect asks the user for information about the current location and 
outputs the resulting time zone description to standard output.</para></sect4>

<sect4><title>xtrace</title>
<para>xtrace traces execution of program by printing the currently executed
function.</para></sect4>

<sect4><title>zdump</title>
<para>zdump is the time zone dumper.</para></sect4>

<sect4><title>zic</title>
<para>zic is the time zone compiler.</para></sect4>

<sect4><title>libc, libc_nonshared, libc_p</title>
<para>These files constitute the main C library.  The C Library is a
collection of commonly used functions in programs.
This way a programmer doesn't need to create his own functions for every
single task. The most common things like writing a string to the screen
are already present and at the disposal of the programmer.</para>

<para>The C library (actually almost every library) come in two flavors:
dynamic ones and static ones. In short when a program uses a static C
library, the code from the C library will be copied into the executable
file. When a program uses a dynamic library, that executable will not
contain the code from the C library, but  instead a routine that loads
the functions from the library at the time the program is run. This
means a significant decrease in the file size of a program. The
documentation that comes with the C Library describes this in more
detail, as it is too complicated to explain here in one or two
lines.</para></sect4>
