[Reposting to mercurial at selecing.com as suggested by Mads]
Thank you Mads,
The contents of the hgweb.config file are:
[collections]
\\mercurial\mercurial = \\mercurial\mercurial
So I'm using collections rather than paths.
The repo http://mercurial:8000/myrepo/include/mysub cannot be accessed.
Supposedly the configuration above should tell hg serve to publish
_any_ folder contained within \\mercurial\mercurial or any of its
folders (recursively). However while it does pickup all mercurial
repos in there (including those that are inside folders), it does not
pickup any subrepos.
I've gone through the Publishing Repositories section of the wiki and
I don't see anything there that might suggest that this is the
expected behavior. If it is then you cannot use collections if you use
subrepos.
Cheers,
Angel
