+.SH DESCRIPTION
+The C++ language provides function overloading, which means that you can
+write many functions with the same name (providing each takes parameters
+of different types).  All C++ function names are encoded into a
+low-level assembly label (this process is known as
+.I mangling\c
+).  The 
+.B @PROGRAM@
+program does the inverse mapping: it decodes (\fIdemangles\fR)
+low-level names into user-level names so that the linker can keep
+these overloaded functions from clashing.
+.PP
+Every alphanumeric word (consisting of letters, digits, underscores,
+dollars, or periods) seen in the input is a potential label.  If the
+label decodes into a C++ name, the C++ name replaces the low-level
+name in the output.
+.PP
+You can use
+.B @PROGRAM@
+to decipher individual symbols by specifying these symbols on the
+command line.
+.PP
+If no
+.B symbol
+arguments are given,
+.B @PROGRAM@
+reads symbol names from the standard input and writes the demangled
+names to the standard output.  All results are printed on the standard
+output.
+.SH OPTIONS
+.TP
+.B \-_
+.TP
+.B \-\-strip\-underscores
+On some systems, both the C and C++ compilers put an
+underscore in front of every name.  For example, the C name 
+.B foo
+gets the low-level name 
+.BR _foo .
+This option removes the leading underscore.
+
+.TP
+.B "\-s {gnu,lucid,arm}"
+.TP
+.B \-\-format={gnu,lucid,arm}
+GNU
+.B nm
+can decode three different methods of mangling, used by different C++
+compilers.  This option selects which method it uses: the one used by
+the GNU compiler, the one used by the Lucid compiler, or the one
+specified by the C++ Annotated Reference Manual.  The default is the
+GNU style.
