	Lol :-) the perl is mangled enough that I suspect you can be productive
like that just fine to start with.

	The basic idea is that make_installer is like 'make install' in a
normal package; but instead of working from a Makefile, it gets its data
from an 'inf' or 'ins' file - which is a flat script-like thing that is
built and delivered from 'scp2'.

	The pedigree of this, is that we used to have a StarBasic installer
that was similiar and ... [well anyway ;-]. So this was some sort of
incremental step and improvement, away from that.

	Great.

	Heh - we ask for a dual LGPLv3+ -and- MPL license for changes; so
LGPLv3+/MPL is the question :-)

	Thanks again ! (and any more joy with the profiler ?),

	Incidentally, I suspect that the profiler may not show you
inefficiencies from forked children; you may see some more 'fun' by
running under 'strace -f -e execve perl .../make_installer.pl' or
somesuch - we had some zip related cleanups avoiding spawning lots of
processes (helping Windows where that is deadly slow) in the past - but
no doubt more silliness can be seen that way.

	ATB,

		Michael.
