Re: [Wigwam-devel] projectctl and autoconf/automake

[Michael R. <mr...@bl...>]

I see.  Since the default has changed, the docs should really mention
that the only safe way to have automatic rebuilding is to install
autotools in the project.

Checking in the configure script does seem safe and reasonable.

Along that line, it also seems like there's such a short leap between
"project source code" and "a package in a local package archive whose
source happens to be in the project" that maybe wigwam4 should provide
tools to make the latter easy, so projectctl is no longer necessary, and
there can be stable releases of in-project libraries/services without
using branches.  (Hmm, actually that won't be so hard...maybe I'll do it
that way under wigwam 3.)
