Re: [help-GIFT] Optimizing

[Wolfgang Mueller]

Dear Julia, Dear David, diear all,

I am not able to seriously review patches in the next few days (I did
say so, right ;-) ). However, though I am not a pure fan of the kind of deal
proposed below, I suggest the following.

1) we accept your patches, with the possibility of later changing the
most hairraising hardcodings
2) someone do some hacks to my perl (possibly with my help) to make
multiple feature extactors peacefully coexist.
3) if it turns out that your patches are really bad for some purposes
and cannot be cured without losing the speed advantages, we add a more
conservative version back to the tree.

Sounds good to both/all of you?

Cheers,
Wolfgang
