+.B \-\-no\-demangle
+These options control whether to demangle symbol names in error
+messages and other output. When the linker is told to demangle, it
+tries to present symbol names in a readable fashion: it strips leading
+underscores if they are used by the object file format, and converts
+C++ mangled symbol names into user readable names. The linker will
+demangle by default unless the environment variable
+.B COLLECT_NO_DEMANGLE
+is set. These options may be used to override the default.
