#NAME

SelectSaver - save and restore selected file handle

#SYNOPSIS

use SelectSaver;

{
   my $saver = new SelectSaver(FILEHANDLE);
   # FILEHANDLE is selected
}
# previous handle is selected

{
   my $saver = new SelectSaver;
   # new handle may be selected, or not
}
# previous handle is selected

#DESCRIPTION

A SelectSaver object contains a reference to the file handle that was selected when it was created. If its new method gets an extra parameter, then that parameter is selected; otherwise, the selected file handle remains unchanged.

When a SelectSaver is destroyed, it re-selects the file handle that was selected when it was created.
