hg convert using regexp in the filemap

[Uwe Brauer]

Hi

I would like to extract a subdirectory from my main repository. That subdirectory contains another subdirectory, that contains images, jpg and png

So https://heavymetaldev.com/hg-repo-conversion

I tried 
include r:regex/Folien/teil3/images/*
include r:regex/Folien/teil3/images2/*
include r:regex/Folien/teil3/images3/*
include Folien/teil3/master-iq.tex

But the files in the images directories were not included

I also tried

include r:regex/Folien/teil3/images/.*/include
include r:regex/Folien/teil3/images2/.*/include
include r:regex/Folien/teil3/images3/.*/include
include Folien/teil3/master-iq.tex

Did not work. What do I miss?

Thanks and regards
