(Almost) all extensions together in one place

Ironically, I deliberately chose to put absolute repo URLs in .hgsub
because I did not want to clutter up hg.gerg.ca's front page with 40
or 50 or 60 clones of other people's extensions.  And because I don't
want to maintain all those clones.  But now I'm stuck with "hg push"
recursing over 37 subrepos that I have no intention of committing or
pushing to. Count me in as another vote for read-only subrepos!

Hmmmm.  I want to limit this to extensions with a cloneable URL on the
public Internet.  I'm sure there are bazillions of private extensions
out there that implement XYZ Corp's own weird policy, but they are out
of scope for allextensions.

So your hypothetical 'missing' script could find extensions you have
configured, and if you have configured by pointing extensions.foo at
your local clone of foo, and that clone has paths.default set, then we
can guess "ah-ha! here is a URL for the foo extension".  But then it
will take some sort of intervention to decide if that URL is suitable
for adding to allextensions.

OTOH, maybe I should just stick with my current restrictive policy: if
it's not listed in the Mercurial wiki, it doesn't go in allextensions.

Well, if you happen to have a copy of Mercurial 1.2 (pre-subrepos)
around you could clone it with that.  ;-)

Yeah, my secret agenda here is to get people to agree on some common
metadata for extensions in the wiki.  Here is my proposal:

  Repository: <public http url that I can pass to hg clone>
  Other info: <public http url to blog post, project home page, wiki, whatever>

Every extension should provide "Repository".  Many extensions commonly
use "Download site" for the cloneable URL, which I think is
misleading.  I propose changing every occurrence of "Download site"
that references a cloneable URL to "Repository".

If no one objects, I'll probably do some incredibly tedious and
mind-numbing wiki-search-and-replace over the weekend.  Wheeee fun.

I don't believe there really IS a GAS SHORTAGE.. I think it's all just
a BIG HOAX on the part of the plastic sign salesmen -- to sell more numbers!!
