| 32 | <application>Lua</application> is a powerful light-weight programming
|
---|
| 33 | language designed for extending applications. It is also frequently used
|
---|
| 34 | as a general-purpose, stand-alone language. <application>Lua</application>
|
---|
| 35 | is implemented as a small library of C functions, written in ANSI C, and
|
---|
| 36 | compiles unmodified in all known platforms. The implementation goals are
|
---|
| 37 | simplicity, efficiency, portability, and low embedding cost. The result is
|
---|
| 38 | a fast language engine with small footprint, making it ideal in embedded
|
---|
| 39 | systems too.
