// 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
