-// 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
