"""

Checks that all of the "catch_foo_all.hpp" headers include all subheaders.
|
|
|
|
The logic is simple: given a folder, e.g. `catch2/matchers`, then the
|
|
ccorresponding header is called `catch_matchers_all.hpp` and contains
|
|
* all headers in `catch2/matchers`,
|
|
* all headers in `catch2/matchers/{internal, detail}`,
|
|
* all convenience catch_matchers_*_all.hpp headers from any non-internal subfolders
|
|
|
|
The top level header is called `catch_all.hpp`.
