This is a small (one module), well tested library for working with semantic versions (see [http://semver.org] for more details).
Until this project has been bootstrapped to use libconf, you will need to use either the embedded version of rebar, or compile it from source using the fork/branch here.
First you must bootstrap the build system using the init.config settings.
% ./rebar -C init.config get-deps compile
Then you can fetch and build all the required dependencies:
% ./rebar get-deps compile
If you want to run the test suites, you can do so any time after after you've bootstrapped, like so:
% ./rebar -C test.config test -v
