+=head1 CAVEATS
+
+It seems that using Term::ReadLine from Emacs minibuffer doesn't work
+quite right and one will get an error message like
+
+ Cannot open /dev/tty for read at ...
+
+One possible workaround for this is to explicitly open /dev/tty like this
+
+ open (FH, "/dev/tty" )
+ or eval 'sub Term::ReadLine::findConsole { ("&STDIN", "&STDERR") }';
+ die $@ if $@;
+ close (FH);
+
+or you can try using the 4-argument form of Term::ReadLine->new().
