Move the documentation from Documentation/technical/api-submodule-config.txt to submodule-config.h as it's easier for the developers to find the usage information beside the code instead of looking for it in another doc file. Documentation/technical/api-submodule-config.txt is removed because the information it has is now redundant and it'll be hard to keep it up to date and synchronized with the documentation in the header file. The documentation of parse_submodule_config_option() is discarded as the function was removed 2 years ago.

/**
|
|
* The submodule config cache API allows to read submodule
|
|
* configurations/information from specified revisions. Internally
|
|
* information is lazily read into a cache that is used to avoid
|
|
* unnecessary parsing of the same .gitmodules files. Lookups can be done by
|
|
* submodule path or name.
|
|
*
|
|
* Usage
|
|
* -----
|
|
*
|
|
* 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. If the
|
|
* caller does only want to lookup values from revisions the initialization
|
|
* can be skipped.
|
|
*
|
|
* If the internal cache might grow too big or when the caller is done with
|
|
* the API, all internally cached values can be freed with submodule_free().
|
|
