* Create apdf-6.0.0.toml
* Update apdf-6.0.0.toml
Just triggering a new automated test (archive name was wrong on SF).
* Update apdf-6.0.0.toml
Added some demos as executables (for `alr run`)
Also applied the rest of transformations described in alire#227: no top-level
[genera] table, name/version keys, [[depends-on]] array instead of table.
Crates without maintainer or pending migration remain in /orphaned
GitHub URLs rely on the default tarballs that at some point will
have to be released with uploaded binaries (with `alr publish` support).
