-// File:
-//     ProgramOptions.h
-//
-// Purpose:
-//     A representation of options for any program.
-//
-// History:
-//     08/08/95 - adve  - Created in the dHPF compiler
-//      10/10/96 - mpal, dbaker - converted to const member functions.
-//      10/19/96 - meven - slightly changed interface to accomodate 
-//                         arguments other than -X type options
-//     07/15/01 - vadve - Copied to LLVM system and modified
