 \subsection{log\_msg and log\_xxd}
 
-pcsc-lite provides two functions that can be used to log debug messages.
-You \emph{should not} use these functions unless you know what you do.
-You should not use \texttt{log\_msg()} directly but use the macros
-defined in \texttt{/usr/include/PCSC/debuglog.h}.
+The \texttt{pcscd} daemon (part of pcsc-lite) provides two functions
+that can be used to log debug messages. You should not use
+\texttt{log\_msg()} directly but use the macros defined in
+\texttt{/usr/include/PCSC/debuglog.h}.
 
-These logging functions are used by some IFD handlers to benefit from
-the log framework offered by \texttt{pcscd} (the daemon).
+These logging functions are used by some IFD handlers (smart card
+driver) like the CCID driver
+\url{http://pcsclite.alioth.debian.org/ccid.html} to benefit from the
+log framework offered by \texttt{pcscd} (the daemon). With these
+functions it is easy to change the log level (debug, info, error or
+critical) and the log output (syslog or stderr) without recompiling the
+driver.
 
-These logging functions are also used by \texttt{libmusclecard} to log
-some internal information and errors. You have to define the environment
-variable \texttt{MUSCLECARD\_DEBUG} to activate the debug on the client
-side.
