+# LibreOffice API IDL Files Except UDK API
+
+Contains all of the IDL files except those in `udkapi`.
+
+i.e. the interfaces that are specific to the LibreOffice application.
+An artificial (?) separation.
+
+The reference `offapi/type_reference/offapi.idl` and
+`udkapi/type_reference/udkapi.idl` (formerly combined into a single
+`offapi/type_reference/types.rdb`) are used to detect inadvertent incompatible
+changes.  They are plain-text `.idl` files (not strictly lexicographically sorted,
+though, so they satisfy the `.idl` file requirements for no forward dependencies),
+so in cases where we deliberately /do/ become incompatible they can be modified
+manually.
+
+Old such cases of deliberately becoming incompatible are listed in
+`offapi/type_reference/typelibrary_history.txt`, newer such cases are recorded in
+the `git log`s of (now superseded) `offapi/type_reference/types.rdb`,
+`offapi/type_reference/offapi.rdb`, and `udkapi/type_reference/udkapi.rdb`, new such
+cases are recorded in the `git log`s of `offapi/type_reference/offapi.idl` and
+`udkapi/type_reference/udkapi.idl`.
