Pulleyback: add commit() and rollback() to instance methods.

[steamworks] / README

This repository holds notes and code for the initial implementation
of parts of the SteamWorks system, in particular the Crank, Shaft and
Pulley parts of that system.

    docs/                Holds project documentation
    src/                 Project sources
    src/3rdparty         Third-party imported sources
    src/common           Support code, common components
    src/crank            Steamworks Crank component

See LICENSE for overall licensing information, and a README in each 
subdirectory for local details. See README.<os> for details regarding 
SteamWorks on a particular operating system and for build dependencies. 
For a quick start (assuming the build dependencies are met; otherwise 
you will get error messages that point out what is missing), just run

    make

to create a build directory, configure and build the system.

The documentation is written in MarkDown. There is a docs/Makefile that 
will produce nicer output using ronn(1).

For example usage of the system, see the examples/ directories in the 
various components directories. These contain example data and scenario's 
to demonstrate the system; you will need to read some of the documentation 
in docs/ to know what to do with them.
