and several redirects for moved main arch pages
Problems:
- The documentation lacks hierarchy
- Relocating pages disrupts external links to
the documentation and causes confusion for users
Benefits:
- Users can easily access relocated pages from external resources
- Using redirects frees up options for reorganizing the documentation
The solution:
- Introduced directive `alias` which declares previous path of
a moved document as the argument.
- Redirects are implemented with Sphinx extension rediraffe_redirects.
