30 ;; This file contains wrappers for every semantic-function and -variable used
31 ;; by ECB independent which semantic version is used. So the ECB-code is
32 ;; independent from the fact, if semantic 2.0 offers backward-compatibility or
33 ;; not. This library offers for each variable V of semantic a getter-function
34 ;; named "ecb--V" and for each function F an alias named "ecb--F". V and F
35 ;; follow the naming conventiones of semantic 2.0 but the resulting functions
36 ;; always point to the correct variable or function of semantic independent
37 ;; which semantic version is loaded. ECB only uses the functions exported from
38 ;; ecb-semantic-wrapper.el!
