Jeff,

i try to do that, though most people probably don't really care either way as
long as things work as desired :-)

it is getting late (here --- for me at least) and I will be unable to
substantially answer any of the remaining or earlier posts nonight and perhaps
not even tomorrow. i have started to answer your first post (perhaps that goes
out tonight though)

so on this one (thank you for it) only two or three small bits

they can though they should not distribute it under the license

i'm human and yes we screw up

you have that right, and i now see that it was a mistake to change in the
license the reference from cfgguide.tex to modguide.tex it should either refer
to both or perhaps modguide could do with some update

from cfg guide:

\subsection{Examples}

Since we have been prompted, despite our misgivings, to document how
to do this by members of the League for Programming Freedom, it seems
appropriate to describe here a possible modification of \LaTeX{} to
produce a system called fsf\TeX.

To do this, you should create a file called \texttt{fsftex.tex} and
then run it using \iniTeX{} and the standard \LaTeX{} format.

The contents of the file \texttt{fsftex.tex} should be as shown on
page \pageref{fsfcode}.  The particular changes to the \LaTeX{} kernel
that you wish to make need to be added to the file at the position
indicated.  You can also choose the extensions you want to use for the
class and package files in your system.

they may have resource (including Leslie Lamport these days) but that doesn't

not yet there (later this week)

going into that some other time

as such a user perhaps doesn't :-) though if you take the view on a
stand-alone program most programmer take the view that their programming
effort (at leats at major release cycles9 is geared towards a stable system.

now the point that i was trying to make is latex (the thing that is not just
latex kernel but all types of stuff on say CTAN) is a system that actually
becomes a program not on a single machine but on a collection ofmachines that
have to work together. a comparison would would to have gcc inserting code
generation snippets for different architectures into the generated binary
which would render the results in most cases useless.

no certainly not. and i don't belong to the class of Tex users that cross
themselves hearing his name and bless his path --- though i very value his
work and think the very fact that he made TeX so stable amd unchangable
(without a name change) has been very beneficial to the whole community
(including a lot of free software projects that used one form of TeX or the
other)

oh sure, I said "one of the early ones" and again. my claim is that TeX as
sort of a "web" system involving many machines is different from an operating
system which is essentially involving a single machine

did i say that in few words? I hope not

completely different intention (see other post (in case i ever come to it))

agreed and not agreed (again for later)

yes, isn't that's it? :-) (or perhaps even without a smiley?)

it is a good question what makes X special here --- but note, LPPL is not
really so important for the kernel of LaTeX, it is there for helping all the
extensions to stay usable.

anyway, you can do so too, just start your own LaTeX package (from any of
mine) then everybody can enjoy using either of them ...

good night
