Re: [mh] DateTime::Locale

Thanks Brian,

I can understand the original philosophy. For future reference how would 
one adjust the mh include list to make sure that my modules are used? I 
guess what I am asking as I'm not that familiar with the guts of mh is 
where the include list is and can it be easily edited or is it 
distributed throughout the code?

Paul

BTW, There is a LOT of mh's core code that I do not use so I would not 
recommend simply assuming that the shipped Locale.pm doesn't have some 
modification that some part of mh requires based on my success with 
replacing it. I may well find I have broken some other part of mh but 
simply don't use it... YET.
