expand_aliases-0.1 (mediawiki calls these templates)

[boud]

hi samizdat-devel,

Something which is very powerful in mediawiki is what they call templates,
e.g. http://en.wikipedia.org/wiki/Template:NPOV


Here i've included a very primitive version of this. i'm not really sure
what a good name should be (for clarity, to avoid confusion with related
notions, etc etc.) For the moment i'm calling it expand_aliases, but i 
think it should be changed reasonably early if we have a good reason to.

This is clearly a hack only useful while the number of "aliases" remains
very small and maintainable by sysadmin. So then my questions would be:

* should aliases be openly publishable? (on wikipedia many are semi-protected)
* should they be in the config file?
  in an additional config file in yaml format?

i also was wondering whether these aliases should be xml-ised?
e.g. <LZR> instead of {{LZR}} to be cleaned up by html tidy into
<LZR /> except that it gets expanded anyway. But this might teach bad
habits, get people confused about what's a standard xml command or not 
etc etc. Namespaces need to be kept separate.

Anyway, here it is - a rough hack but it does seem to work for anyone
needing a quick hack. (And might inspire something more sensible).

cheers
boud
