When requiring luapath, $HOME/luapath is added to lua path. Lua is then able to find $HOME/luapath/*.lua modules and $HOME/luapath/*/init.lua packages.

Example usage:

# Creating ~/luapath and adding symlinks there
mkdir ~/luapath
cd ~/luapath
ln -s path/to/mymodule.lua
ln -s path/to/mypackage

# Running with luapath
luajit -lluapath mycode.lua
