.SH NAME
-pwd \- Return the current working directory
+pwd \- Return the absolute path of the current working directory
.SH SYNOPSIS
\fBpwd\fR
.BE
.SH DESCRIPTION
.PP
-Returns the path name of the current working directory.
+Returns the absolute path name of the current working directory.
+.SH EXAMPLE
+Sometimes it is useful to change to a known directory when running
+some external command using \fBexec\fR, but it is important to keep
+the application usually running in the directory that it was started
+in (unless the user specifies otherwise) since that minimises user
+confusion. The way to do this is to save the current directory while
+the external command is being run:
+.CS
+set tarFile [file normalize somefile.tar]
+set savedDir [\fBpwd\fR]
+cd /tmp
+exec tar -xf $tarFile
+cd $savedDir
