This directory is used for some tests. As standard Lua has no command to create directories, it must be present before running the tests.
The result of 'string.format("%a", 0.0)' can have multiple zeros after the dot.
This is the first commit for the branch Lua 5.3. All source files were copied from the official distribution of 5.3.5 in the Lua site. The test files are the same of 5.3.4. The manual came from the previous RCS repository, revision 1.167.1.2.
