The "repolist-skin" setting:
If non-zero then use this repository as the skin for a repository list
such as created by the one of:
1) fossil server DIRECTORY --repolist
2) fossil ui DIRECTORY --repolist
3) fossil http DIRECTORY --repolist
4) (The "repolist" option in a CGI script)
5) fossil all ui
6) fossil all server
All repositories are searched (in lexicographical order) and the first
repository with a non-zero "repolist-skin" value is used as the skin
for the repository list page. If none of the repositories on the list
have a non-zero "repolist-skin" setting then the repository list is
displayed using unadorned HTML ("skinless").
If repolist-skin has a value of 2, then the repository is omitted from
the list in use cases 1 through 4, but not for 5 and 6.
