Very impressive - there is a lot of work here! But why? They explain it in docs/latina.h.md |

In include/latina.h, they use the C preprocessor to redefine the C keywords in Latin. Also, many numeric constants -- instead of 4096 you write MMMMXCVI.

The other files in docs explain each library routine in English, but the code samples are in Latin. The source files - a lot of them! - are in include and lib. The code is all in Latin, including the error messages and comments.
