[LUA 5.1] package.path
The path used by require to search for a Lua loader.
At start-up, Lua initializes this variable with the value of the environment variable LUA_PATH or with a default path defined in luaconf.h, if the environment variable is not defined.
Any ";;" in the value of the environment variable is replaced by the default path.
A path is a sequence of templates separated by semicolons.
For each template, require will change each interrogation mark in the template by filename, which is modname with each dot replaced by a "directory separator" (such as "/" in Unix); then it will try to load the resulting file name.
So, for instance, if the Lua path is
the search for a Lua loader for module foo will try to load the files ./foo.lua, ./foo.lc, and /usr/local/foo/init.lua, in that order.
