Central index.html for multi project build

[Kaiser1989]

Expected Behavior

When buildings pdoc for multiple projects with pdoc --html project-a project-b project-c i would expect to get a single documentation containing docs for all 3 projects. Meaning one central index.html and links between all of them.

Actual Behavior

I get 3 folders with docs for each project seperately. There is no way to combine them. Links are working as expected, but i'm missing a starting index.html

Steps to Reproduce

1. Create 3 projects (project-a, project-b, project-c)
2. pdoc --html project-a project-b project-c

Additional info

• python version: 3.8.2
• pdoc version: 0.9.2

Usecase

I provide some python sdk for native libraries, where some packages are used as base packages, to sum up functions used in other packages. We are doing the same for Java, Rust & C. As our packages are build on each other, it would be nice to include other packages to documentation as well, so users do not have to load the docs for each package seperately.

Javadoc & Doxygen are supporting such combinations:

• You can define multiple source inputs, building a single documentation out of it

Any ideas how this can be realized?
