I have discussed in private with the author of that
email afterwards. Though the static typing (java) may
ease the development at first sight, there are some
things that are not possible to do in those languages
(like executing scripts, or getting a fast startup
time). I am myself a strong proponent of Ocaml, but
python is definitely a right tool for this particular
task and scons comes with many good concepts and code
already.

To illustrate this, i have made a (quite naive)
reimplementation of the algorithm that scans folders
for files: it takes about three seconds to scan or
replicate a project containing 1000 folders (of two
files each), not more than a minute. The weak typing
is a bad excuse for the wrong code.

Thomas
