Oddmuse <http://www.oddmuse.org/> is a good candidate. It's Perl+flat
file, reasonably simple to use and maintain.
Depending on your needs, you might also consider TiddlyWiki
<http://www.tiddlywiki.com/>, which is implemented entirely in
client-side JavaScript, stored in a single HTML file which includes the
script and the data. There are many add-ons and customizations for it,
and there are ways to save it to the local filesystem and/or a "ServerSide".
Probably unsuitable, but including it for completeness' sake: Sig Wik
<http://c2.com/cgi/wiki?SigWik>, which is implemented in 222 characters
of Perl.

Can anyone recommend a really lightweight Wiki?
Preferably PHP but flat file
would be considered too.
