+ * TclFileAttrsCmd --
+ *
+ *      Sets or gets the platform-specific attributes of a file. The objc-objv
+ *	points to the file name with the rest of the command line following.
+ *	This routine uses platform-specific tables of option strings
+ *	and callbacks. The callback to get the attributes take three
+ *	parameters:
+ *	    Tcl_Interp *interp;	    The interp to report errors with.
+ *				    Since this is an object-based API,
+ *				    the object form of the result should be
+ *				    used.
+ *	    CONST char *fileName;   This is extracted using
+ *				    Tcl_TranslateFileName.
+ *	    TclObj **attrObjPtrPtr; A new object to hold the attribute
+ *				    is allocated and put here.
+ *	The first two parameters of the callback used to write out the
+ *	attributes are the same. The third parameter is:
+ *	    CONST *attrObjPtr;	    A pointer to the object that has
+ *				    the new attribute.
+ *	They both return standard TCL errors; if the routine to get
+ *	an attribute fails, no object is allocated and *attrObjPtrPtr
+ *	is unchanged.
+ *
+ * Results:
+ *      Standard TCL error.
+ *
+ * Side effects:
+ *      May set file attributes for the file name.
