@Leah Hanson Note that helpdb.jl is autogenerated from the .rst files. doc/stdlib/base.rst <https://raw.githubusercontent.com/JuliaLang/julia/master/doc/stdlib/base.rst> now contains the documentation, so it should be included in upcoming releases. There is a problem where some versions of spinx generate extra newlines for the helpdb file, so many developers are unable to regenerate the file. It will likely happen soon.
