\&\fBpaclog\fR determines whether or not to read the log file from \fIstdin\fR based on
a naive check using \fBisatty\fR\|(3).  If \fBpaclog\fR is called in an environment,
such as a shell function or script being used in a pipe, where \fIstdin\fR is not
connected to a terminal but does not a log file to parse, \fBpaclog\fR should be
called with \fIstdin\fR closed.  For POSIX-compatible shells, this can be done
with \f(CW\*(C`<&\-\*(C'\fR.
