- fixes SIGINT (ctrl+c) for 'dub -b ddox'

Let "*" match any version or branch. Fixes #151.

Add the test packages to the Travis CI script. See #287.

Fix an error in the dependency resolution due to a signed/unsigned comparison. See #285. ...

Also added some diagnostic output to the dependency resolution algorithm.

Make log parameters lazy instead of auto ref. ...

This enables passing arguments doing complex computations for debug messages without worrying about impacting execution speed when debug logging is disabled.

Resolve sub packages of the root package directly instead of using the package manager. Fixes #287.

Add path based sub packages to Package.m_subPackages, too.

Fix null pointer dereference in Project.this() when no package was found. Fixes #286.

Avoid exponential run time in the dependency resolution algorithm if possible. ...

When going through all combinations of package versions, all sub trees of the search space are now skipped for a conflicting node, as those are guaranteed to conflict anyway.

Handle packages with invalid package descriptions gracefully and improve diagnostic output.

Fix compilation on DMD 2.064.

Fix path based dependencies to be ignored for version selections.

Fix unit tests of DependencyResolver.

Let Dependency.toString() also contain the optional/path properties. ...

versionString is changed into a public property to support the use cases where only the version range is expected.

Fix resolution of optional and path based dependencies.

Disable log output during "dub describe" to ensure only JSON gets written. See #221. ...

Note that JSON will only get written when no errors occur. Otherwise the output will be the usual error messages.

Add command line interface for managing package overrides.

Correct copyright notices.

Mention using DUB as a library.

Refactor runDubCommandLine to use less indentation/nesting.

Implement user/system wide overriding of certain package version ranges. ...

What is still missing is a command line interface for conveniently setting the overrides.

Fix getting the versions of each package during dependency graph resolution.

Generate less noise for up to date dependencies.

Only validate (and output warnings) the root package once.

Reinitialize the project after upgrading dependencies.

Output -l flags on the compiler command line after all source files. Fixes #281.

Fix handling of overriding selections and let printUpgradesOnly fail gracefully.

Improve the warning message for branch based dependencies.

Fix dependency resolution for outdated invalid dependencies. ...

Now the invalid dependency is simply ignored as long as it isn't actually chosen.

Add a warning message for packages that use branch based dependencies.
