[galaxy-dev] Wiki documentation for tool_dependencies.xml file

Hi all, Is there a page on the wiki describing the tool_dependencies.xml file syntax? Searching finds pages with examples, e.g. https://wiki.galaxyproject.org/ToolsWithDependenciesInSameRepository https://wiki.galaxyproject.org/ComplexRepositoryDependencies What I am looking for is something like the wiki page for the tool XML: https://wiki.galaxyproject.org/Admin/Tools/ToolConfigSyntax This missing page should do things like list all the XML tags, for example showing all the permitted actions in tool_dependencies.xml? What are the pre-defined environment variables like $INSTALL_DIR, and my specific question today - does that have a trailing slash or not? Peter
