61 its main body. I.e., if this is file "foo.cc", and class `bar'
62 is defined in "foo.cc", then we say that "foo.cc implements bar".
64 All main input files "implement" themselves automagically.
66 `#pragma interface' means that unless this file (of the form "foo.h"
67 is not presently being included by file "foo.cc", the
68 CLASSTYPE_INTERFACE_ONLY bit gets set. The effect is that none
69 of the vtables nor any of the inline functions defined in foo.h
72 There are cases when we want to link files such as "defs.h" and
73 "main.cc". In this case, we give "defs.h" a `#pragma interface',
