Make the dependency test packages compile on Windows.

Fix JSON unit test for 2.068.

Fix compilation and CI test on DMD 2.068-b1. Fixes #541.

Merge pull request #612 from D-Programming-Language/sdl-init ...

Add SDL support to "dub init".

Fix help text formatting.

Merge pull request #593 from Abscissa/beefy-env ...

Send additional env vars to build commands.

Change delimiter on DUB_PLATFORM/DUB_ARCH to space.

Send additional env vars to build commands.

Add "active" field to "dub describe" output. Fixes #393. Closes #577. ...

The active field determines if a certain dependency takes part in the build process (for the selected build configuration/platform).

Fix line wrapping for the "dub describe" command description.

Add SDL support to "dub init". ...

SDL is now the default format and "-f json" can be used to force JSON.

Merge pull request #607 from D-Programming-Language/refactor1 ...

Improve "dub describe" and use BitFlags

Fixed: Compile error on anything before DMD 2.067.

Fixed: --data=linker-files misses linker files specified in dub.json.

TargetDescriptionGenerator: Don't add linker files to BuildSettings.sourceFiles.

Change order of describe-data tests, list should run before dmd as it's easier to debug.

Again, rework --data's handling of sourceFiles and static library dependencies.

Skip DMD-centric tests when DMD isn't available.

Rework --data's handling of sourceFiles and static library dependencies.

Accidentally left in some old commented-out code.

Make targetLookup return an index into targets[], instead of a redundant set of data.

buildPath -> buildNormalizedPath

Replace 'getBuildSettingBitField' with 'to!BuildSetting'.

Allow comma-separated list in --data, for brevity.

Add --data-0 to output --data= info null-delimited for (ex.) xargs -0

Fixed: When formatting output for a compiler, if the package is a library or a staticLibrary, then --data=libs never emits any output.

Replace --data-format with --compiler and --data-list.

Add 'dub describe --data-format=' to format the output of --data= directly for a compiler's commandline. Use --data-format=list to get the old list-style output.

Split --data=libs into two: --data=libs (for installed/system libs) and --data=lib-files (for dependency libs) ...

This is needed because compilers/linkers often expect the two types of libs to be passed in differently: System/installed libs (--data=libs) must be provided like "-Lname" which the linker automatically converts to "path/lib*.a". Non-installed libs, such as dub dependencies, are passed with full filepath just like an object file. Your linker may vary.

Add 'dub describe --data='.
