+@item --long-section-names @{enable,disable,keep@}
+Controls the handling of long section names when processing @code{COFF}
+and @code{PE-COFF} object formats.  The default behaviour, @samp{keep},
+is to preserve long section names if any are present in the input file.
+The @samp{enable} and @samp{disable} options forcibly enable or disable
+the use of long section names in the output object; when @samp{disable}
+is in effect, any long section names in the input object will be truncated.
+The @samp{enable} option will only emit long section names if any are
+present in the inputs; this is mostly the same as @samp{keep}, but it
+is left undefined whether the @samp{enable} option might force the 
+creation of an empty string table in the output file.
