+This library makes libuv available to lua scripts. It was made for the luvit
+project but should usable from nearly any lua project.
+
+The library can be used by multiple threads at once. Each thread is assumed to
+load the library from a different lua_State. Luv will create a unique uv_loop_t
+for each state. You can't share uv handles between states/loops.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
