66 %% Config processing functions are annotated with TOML paths
67 %% Path syntax: dotted, like TOML keys with the following additions:
68 %% - '[]' denotes an element in a list
69 %% - '( ... )' encloses an optional prefix
70 %% - '*' is a wildcard for names - usually that name is passed as an argument
71 %% If the path is the same as for the previous function, it is not repeated.
72 %%
73 %% Example: (host_config[].)access.*
74 %% Meaning: either a key in the 'access' section, e.g.
75 %% [access]
76 %% local = ...
77 %% or the same, but prefixed for a specific host, e.g.
78 %% [[host_config]]
79 %% host = "myhost"
80 %% host_config.access
81 %% local = ...
