Package txscript implements the bitcoin transaction script language. There is a
comprehensive test suite.

This package has intentionally been designed so it can be used as a standalone
package for any projects needing to use or validate bitcoin transaction scripts.

## Bitcoin Scripts

Bitcoin provides a stack-based, FORTH-like language for the scripts in the
bitcoin transactions. This language is not turing complete although it is still
fairly powerful. A description of the language can be found
at https://en.bitcoin.it/wiki/Script

## Installation and Updating

$ go get -u github.com/p9c/p9/txscript
