I encouraged Mr. Enage to introduce himself on this mailing list as a
potential maintainer for the Parameter library. His PR for the Parameter
library, at, convinced me
that he could be a worthy maintainer for that library, which currently
has no official maintainer of which I know. I have always been impressed
by the work of David Abrahams and Daniel Wallin in creating the library,
and although others have made some small fixes to the library over the
years I think it would be greatly to Boost's benefit if someone who had
experience with the library and who had a willingness to maintain and
improve the library, as Mr. Enage clearly has, could step forth and
clearly do so.
