CXXDEMANGLE
 The CXXDEMANGLE command enables you to decode compiler-generated names. 
 To accomplish this, CXXDEMANGLE uses a data file created by the C++ 
 compiler when you compile a program.  The data file contains a 
 mapping of symbol names from their encoded to decoded forms.
 When asked to decode a name that is not the data file, CXXDEMANGLE
 returns the original name.
 CXXDEMANGLE provides two interfaces: a command line interface and an 
 interactive interface.  
 o To use the command line interface, enter the CXXDEMANGLE command followed
   by a comma-separated list of symbol names in their mangled form.  
   CXXDEMANGLE then displays the demangled form of each symbol and exits.   
   The syntax for the command line interface is:
   CXXDEMANGLE mangled-symbol-name [,...]
 o To use the interactive interface, enter the CXXDEMANGLE command without
   specifying a symbol name.  CXXDEMANGLE then waits for you to enter a
   symbol name in its mangled form.  When you enter a symbol, CXXDEMANGLE
   displays the demangled form of the symbol and waits for you to enter
   another symbol, and so forth.  To exit the interactive interface, enter
   <CTRL/Z>.  The syntax for the interactive interface is:
      CXXDEMANGLE
      mangled-symbol-name
      [...]
      <CRTL/Z>
