+short_desc="Small, compilable scripting language providing easy access to C code"
+desc="Lua is a programming language originally designed for extending applications,
+but also frequently used as a general-purpose, stand-alone language. Lua
+combines simple procedural syntax (similar to Pascal) with powerful data
+description constructs based on associative arrays and extensible semantics.
+Lua is dynamically typed, interpreted from bytecodes, and has automatic memory
+management with garbage collection, making it ideal for configuration,
+scripting, and rapid prototyping. 
+
+A fundamental concept in the design of Lua is to provide meta-mechanisms for
+implementing features, instead of providing a host of features directly in
+the language. For example, although Lua is not a pure object-oriented
+language, it does provide meta-mechanisms for implementing classes and
+inheritance. Lua's meta-mechanisms bring an economy of concepts and keep the
+language small, while allowing the semantics to be extended in unconventional
+ways. Extensible semantics is a distinguishing feature of Lua. 
+
+Lua is implemented as a small library of C functions, written in ANSI C, and
+compiles unmodified in all known platforms. The implementation goals are
+simplicity, efficiency, portability, and low embedding cost."

+Submitted By:            Xi Ruoyao <xry111 at xry111 dot site>
+Date:                    2022-09-16
+Initial Package Version: 5.4.4
+Upstream Status:         Rejected
+Origin:                  Arch Linux, with some modifications
+Description:             2020-06-30 renodr:
+                         Creates a shared liblua library, as well as
+                         removes optimization since it causes SIGBUS errors,
+                         and sets the search path to /usr from /usr/local.
+                         The initial version of this patch was created by
+                         Igor Zivkovic, before being rediffed for 5.4.0 by
+                         myself with some modifications made.
+                         2022-09-16 xry111:
+                         Remove an extra newline before $(MYLDFLAGS).
+                         MYLDFLAGS is empty by default so it does not break
+                         BLFS build, but it may break a custom build with
+                         tuning or hardening.
