Function createargtable

src/Chain/libraries/glua/lauxlib.cpp:954–964

** Create the 'arg' table, which stores all arguments from the ** command line ('argv'). It should be aligned so that, at index 0, ** it has 'argv[script]', which is the script name. The arguments ** to the script (everything after 'script') go to positive indices; ** other arguments (before the script name) go to negative indices. ** If there is no script name, assume interpreter's name as base.

** If there is no script name, assume interpreter's name as base.
