libuv1 binary package in Ubuntu Mantic armhf

 Libuv is the asynchronous library behind Node.js. Very similar to libevent or
 libev, it provides the main elements for event driven systems: watching and
 waiting for availability in a set of sockets, and some other events like timers
 or asynchronous messages. However, libuv also comes with some other extras
 like:
  * files watchers and asynchronous operations
  * a portable TCP and UDP API, as well as asynchronous DNS resolution
  * processes and threads management, and a portable inter-process
    communications mechanism, with pipes and work queues
  * a plugins mechanism for loading libraries dynamically
  * interface with external libraries that also need to access the I/O.
 .
 This package includes the dynamic library against which you can link
 your program.
