    newprofi.hxx
    Internal details of INI-file handling primitives

    The internal include file contains stuff which needs to go before the
    class definition of INI_FILE_IMAGE, but which clients of this class
    don't need to know about.

    NAME:	PARAMETER

    SYNOPSIS:	Stores an image of a parameter in an INI file, including
		parameter name and parameter value.  The PARAMETER class
		has the property that, as long as the constructor
		succeeds (QueryError() == NERR_Success), no subsequent
		method can make the object invalid (short of freeing its
		pointers etc.)  If any Set or SetParamValue operation fails,
		the object snaps back to its original state.

    INTERFACE:	PARAMETER()	- Constructs a parameter.
		~PARAMETER()	- Destructs a parameter.

		SetParamValue()	- Changes the value of the parameter.
		Set()		- Changes the name and value of the parameter.

		QueryParamName()- Asks after the parameter name.
		QueryParamValue()- Asks after the parameter value.

    PARENT:	BASE

    CAVEATS:	This class is meant to be used internally by
    		INI_FILE_IMAGE and is not for direct use by the client.

    NAME:	COMPONENT

    SYNOPSIS:	Stores an image of a component in an INI file, including
		component name and parameter list.  The COMPONENT class
		has the property that, as long as the constructor
		succeeds (QueryError() == NERR_Success), no subsequent
		method can make the object invalid (short of freeing its
		pointers etc.)  If any AppendParam or RemoveParam operation
		fails, the object snaps back to its original state.

    INTERFACE:	COMPONENT()	- Constructs a component.
		~COMPONENT()	- Destructs a component.

		AppendParam()	- Adds a parameter to the component.
		RemoveParam()	- Removes a parameter from the component.
		QueryCompName()	- Asks after the name of the component.
