[MediaWiki-l] three tips hoped

[JFC Morfin]

Hi!
For more than a decade I publish my own working groups, personnal 
uses, etc. wikis. I have hundreds of "bliks": I mean a mediawiki 
under SQLite + mailman + side services.  Each wiki under SQLite can 
be easily transfered to other machines (privare or on line) and 
replicated on several local machines (for private use and backup) in 
using dropbox. The configuration is set-up with a script creating the 
directories, most of them being symbolic links to a main wiki 
configuration, one per machine.

This may sound crazy but it works well.  Now, not being a PHP nor SQL 
programmer I would need help on three issues:

* what is the command to know the mediawiki version I use?
* on different "bliks", i.e. these SQLite supported wikis, I need to 
get the same page (a glossary) to be locally present. Is there a way 
to maintain a page on a single SQLight wiki and to get it replicated 
on others (I just need the current version of the page, not its history) ?
* is there a command I could use (also in a script) to enter 
references to pdf or image files I could then click form wikipages.

Thanks a lot for any help.
