The scripts use now 3rd party Lua modules, e.g. LuaExpat and LuaSocket, which are available for most distros as prebuilt packages. See the README file distributed with libquvi-scripts source code for a more complete list of these modules.
Use of LuaSocket replaces the use of the ‘quvi/url’ module which was licensed under the MIT license, but distributed with the differently licensed 0.4 series (LGPLv2.1+). This ends the era of “distribution of differently licensed code” for libquvi-scripts, as the ‘quvi/url’ is no longer distributed with the 0.9 series.
