/**
* @file
* @brief Crawl Lua test cases
*
* ctest runs Lua tests found in the test directory. The intent here
* is to test parts of Crawl that can be easily tested from within Crawl
* itself (such as LOS). As a side-effect, writing Lua bindings to support
* tests will expand the available Lua bindings. :-)
*
* Tests will run only with Crawl built in its source tree without
* DATA_DIR_PATH set.
