=head1 DESCRIPTION
-C<File::Temp> can be used to create and open temporary files in a safe way.
-The tempfile() function can be used to return the name and the open
-filehandle of a temporary file. The tempdir() function can
-be used to create a temporary directory.
+C<File::Temp> can be used to create and open temporary files in a safe
+way. There is both a function interface and an object-oriented
+interface. The File::Temp constructor or the tempfile() function can
+be used to return the name and the open filehandle of a temporary
+file. The tempdir() function can be used to create a temporary
+directory.
The security aspect of temporary file creation is emphasized such that
a filehandle and filename are returned together. This helps guarantee

+=head1 OO INTERFACE
+
+This is the primary interface for interacting with
+C<File::Temp>. Using the OO interface a temporary file can be created
+when the object is constructed and the file can be removed when the
+object is no longer required.
+
+Note that there is no method to obtain the filehandle from the
+C<File::Temp> object. The object itself acts as a filehandle. Also,
+the object is configured such that it stringifies to the name of the
+temporary file.

+
+by default the object is constructed as if C<tempfile>
+was called without options, but with the additional behaviour
+that the temporary file is removed by the object destructor
+if UNLINK is set to true (the default).
+
+Supported arguments are the same as for C<tempfile>: UNLINK
+(defaulting to true), DIR and SUFFIX. Additionally, the filename
+template is specified using the TEMPLATE option. The OPEN option
+is not supported (the file is always opened).
