`haredo`

This hook uses the haredo command runner to build, check, and install the package. It overrides buildPhase, checkPhase, and installPhase by default.

The hook builds its targets in parallel if enableParallelBuilding is set to true.

`buildPhase`

This phase attempts to build the default target.

Targets can be explicitly set by adding a string to the `haredoBuildTargets` list. This behavior can be disabled by setting `dontUseHaredoBuild` to `true`.

`checkPhase`

This phase searches for the check.do or test.do targets, running them if they exist.

Targets can be explicitly set by adding a string to the `haredoCheckTargets` list. This behavior can be disabled by setting `dontUseHaredoCheck` to `true`.

`installPhase`

This phase attempts to build the install.do target, if it exists.

Targets can be explicitly set by adding a string to the `haredoInstallTargets` list. This behavior can be disabled by setting `dontUseHaredoInstall` to `true`.
