[news.eclipse.modeling.m2t] Re: [MTL] How to reverse lists ?

Hi,

Thanks a lot for using Acceleo
You have to put the tag [Acceleo] at the beginning of the subject (and 
not MTL)
MTL is the name of the OMG standard, so we can understand ;-)
but the name of the eclipse implementation is Acceleo

Cheers,

Jonathan
