 %D Eigner at an NTG meeting, then left it for a while, and sort of finalized it the
 %D last quarter of 2016. As I don't use this module, apart from maybe testing
 %D something, it is not guaranteed to work (but fixing should be a no real problem
-%D as I expect apis to be stable). Plugins liek this can interfere with other
+%D as I expect apis to be stable). Plugins like this can interfere with other
 %D functionality in \CONTEXT\ so don't expect too much support. The two modules
 %D mentioned below should work in the generic loader too. It's anyhow an
 %D illustration of how \type {ffi} be used in a practical application.

+%D I'm not sure if Idris will ever need this but the code has been used for some
+%D articles so that's why it's eventually shipped.
