8 Package txscript implements the bitcoin transaction script language. There is
9 a comprehensive test suite.
11 This package has intentionally been designed so it can be used as a standalone
12 package for any projects needing to use or validate bitcoin transaction scripts.
16 Bitcoin provides a stack-based, FORTH-like language for the scripts in
17 the bitcoin transactions. This language is not turing complete
18 although it is still fairly powerful. A description of the language
19 can be found at https://en.bitcoin.it/wiki/Script
