a couple of tweaks for the Scheme48 build system

[Ivan Shmakov]

I've just made two minor changes to the build system, namely:

• replaced ‘echo > /dev/null’ with ‘:’ (which is the Shell no-op
command) in autogen.sh;

• added a call to the ‘AC_LANG_SOURCE’ macro to
m4/s48_inline.m4, to avoid a gratuitous GNU Autoconf warning.

autogen.sh seems to run correctly with these changes applied.
Please consider committing them to the main Scheme48 repository.

PS. Are there any promotional materials (flyers, posters, videos, etc.)
for Scheme48 that we can show or distribute on SFD 2012, BTW?

I've pushed those changes; thanks!

Unfortunately not. What kind of stuff what you need? (I.e. what would
you want to advertise *for* exactly - users, developers, ...?)

As of the last year (IIRC), most of the participants were Altai
State University students (where the Barnaul's event is held),
including those studying computer science (mostly engineering
aspects of, AIUI.)

An intro into Scheme in general (with examples runnable in
Scheme48) may also be useful (provided that it's short enough so
that we can translate it into Russian in time.) We're planning
to use a network-bootable Debian Wheezy Live to run some 20
computers in a display room, and a version of Scheme48 will
surely be among the available software.

At the very least, I wonder if someone could write a short note
on Scheme48, like the following one we've written on VLC
(translation from Russian is mine):

VLC

Multipurpose free video player, with distinguishing features being
the support of a multitude of formats, the independence of
third-party codecs, the ability to work with stream video (including
webcams), and also the ability to work with different playback
libraries (such as FFmpeg.)

Has numerous and various configuration parameters, but has an
intuitive user interface at the same time.

(We intend to place such short descriptions on the reverses of
our “Join us on SFD-2012!” flyers [1].)

TIA.

Here's my suggestion:

Scheme 48

Implementation of the Scheme programming language for Unix/Linux and
Windows, with an emphasis on a readable and module implementation.
Scheme 48 is itself almost entirely written in Scheme. (Even the VM is
written in the Scheme dialect PreScheme.) Scheme 48 comes with a large
set of libraries and an extensive Foreign Function Interface.

Actually, I'd prefer to omit the operating systems part
completely (since it's quite common for free software to be
cross-platform these days), and rather say that Scheme 48
implements full numeric tower, etc.

I'll send the variant I currently consider (along with its
translation back to English) a bit later. Thanks again for the
one suggested.

PS. I hope that CC BY-SA (as used for the rest of our flyers) is an
acceptable license for this short info.

Absolutely. Consider it public domain.

Well, as Thorsten Glaser noted to me not so long ago [1],
there's no such thing as public domain in certain (and,
arguably, way too many) jurisdictions. (See also [2].)

However, if the intent is to make it “completely” free, then I'd
rather put the end result under CC BY (that is, attribute, but
otherwise use freely.) The Scheme 48 home page URI
(http://s48.org/) will be the attribution.

It appears suitable. However, I don't seem to find the license
information?

Scheme 48 is itself almost entirely written in Scheme. (Even the VM
is written in the Scheme dialect PreScheme.) Scheme 48 comes with a
large set of libraries and an extensive Foreign Function Interface.

Below is the variant I currently consider, translated back to
English. The exact code is MIME'd (please see if the license
header is acceptable; I'm going to change it to CC BY unless
asked not to.) Also to note is that the Git repository is at
[1, 2], and the “working copy” PDF's are at [3, 4].

Scheme 48

Scheme programming language implementation, in whose development an
emphasis was made on code readability and the clarity of the module
system. In development since 1986.

Scheme 48 is almost entirely written in Scheme. Isn't an exception
even the virtual machine it uses, implemented using a Scheme dialect
— PreScheme.

The full numeric hierarchy is supported (including “big” numbers and
common fractions.) The package also includes a large set of
libraries and a fully-featured C language binding.

I'd like to note that (as could be seen from [3, 4]) there's
paper space for a couple more lines of text, which seems to be
enough to hold one another sentence. Any ideas, anyone?

TIA.

As there were no objections, I've pushed the change to the (now
primary) Git repository at Gitorious:
