[web2py] Re: Why admin|examples|welcome in hgignore?

[Wikus van de Merwe]

The intention is not to track changes in user made applications (different 
than the default ones). ?! is the negative lookahead operator, so the first 
part of the expression will match "applications/" only if it is not 
followed with any of the strings in the brackets. The the second part (.*) 
matches everything, so as long as the first part match, the entire sting 
will match too.
