libluv-unix-ocaml 0.5.12-2build3 (s390x binary) in ubuntu noble

 Luv is a binding to libuv, the cross-platform C library that does
 asynchronous I/O in Node.js and runs its main loop.
 .
 Besides asynchronous I/O, libuv also supports multiprocessing and
 multithreading. Multiple event loops can be run in different
 threads. libuv also exposes a lot of other functionality, amounting
 to a full OS API, and an alternative to the standard module Unix.
 .
 This package contains the runtime library of luv_unix, helpers for
 interfacing Luv and Unix.
