Usage
-----
+To initialize the cache with configurations from the worktree the caller
+typically first calls `gitmodules_config()` to read values from the
+worktree .gitmodules and then to overlay the local git config values
+`parse_submodule_config_option()` from the config parsing
+infrastructure.
+
The caller can look up information about submodules by using the
`submodule_from_path()` or `submodule_from_name()` functions. They return
a `struct submodule` which contains the values. The API automatically
-initializes and allocates the needed infrastructure on-demand.
+initializes and allocates the needed infrastructure on-demand. If the

If the internal cache might grow too big or when the caller is done with
