great, so there's a destination repo. :) there's some examples in there, even,
in the various lib/*/examples/ dirs. some questions:
* where should (non-OTP lib using) Erlang examples go? (stdlib/examples?)
* should _every_ lib get an examples/ subdir? (i notice some don't, e.g. edoc)
* should there be a recommended/standardized manner of documenting the
examples? e.g. what each example does? the order to look at the examples in,
if any? i notice, for instance that the gs lib, has a relatively large # of
examples and most of the files are numbered giving an implied order ..
* where would be a reasonable place to publish the extracted set of examples?
(it probably doesn't make much sense to ask people to grab the entire OTP git
repo and explore around in it to get them when a simple archive could be
offered for download...)

not for the sake of the moving things: for the sake of making the docs more
discoverable. perhaps i'm an idiot, but when i looked in the OTP repo the last
place i thought to look was in system/. fortunately find(1) saved me ;)

is this linked anywhere in the index tree on the left side of
http://www.erlang.org/doc/? (i couldn't find it ... and one place i did look
before writing my email was under the Documentation entry .. maybe i just
missed it). it would be very nice imho to find a link on the main page along
with the "Some hints that may get you started faster"
i mentioned book.xml specifically, as it seems to be a convention, and i did
not find a single mention of it in system/doc/. where are OTP documentation
and of course, the users_guide still misses things like how to contribute new
docs to OTP itself ...

if the goal is to make contributing to documentation attractive and easy,
asking potential contributors to set up and build the entire OTP repo build is
if i want to correct something in the documentation, or add a clarifying
phrase / sentence / paragraph, should i really need to not only check out the
OTP git repo but also build it?

that is where one often ends up, and there is no way to trigger the search
there. the actual point i was attempting to make was that contributing
improvements to http://www.erlang.org/doc/ as generated from otp/system/doc/
is not clear and easy. it should, indeed, be simple to provide a link to the
already-provided search capabilities.
(that said ... should perhaps the "Erlang/OTP documentation" link on
http://www.erlang.org/doc.html link to http://www.erlang.org/erldoc? rather
than http://www.erlang.org/doc/? apologies in advance if that's a 'newbie'
question and there is an 'obvious' answer why it is the way it is ... :)
