Re: [Boost-build] project.act-as-jamfile bug?

Yep,

Suppose I could. :) Guess I got caught up in trying to make the jamfile look
like it really was in the directory when I really didn't have to.

As a side note, I took a look at the 1.33.1 boost build and it looks like
someone already caught this as it has a correct in the initialize rule that
uses MATCH to check if the basename is one of JAMROOT. Should've checked this
before posting, I guess. :-P

Thanks,
