Add support for execution result callbacks in the build generator.

Avoid using the deprecated canFind function.

Fix version(Linux) -> version(linux) - gotta love inconsistent naming...

Use --no-as-needed only in Linux (OSX's LLVM based tool chain doesn't support it).

Add --no-as-needed to avoid linker errors with new GCC versions used as the linker front end. See #199.

Put linker flags (including "libs") after linker "sourceFiles". See #199. ...

Supposedly fixes an issue where a dependency that was build as a static library cannot access symbols of an external library that it needs, because the external library is passed to the linker before the dependency itself.

Implement individual building of dependencies.

Rename BuildOptions.noBoundsChecks to noBoundsCheck to be consistent with BuildRequirements.requireBoundsCheck.

Enforce build requirements when generating VisualD projects. Fixes #188.

Rename some BuildOptions to avoid D keywords.

Add support for a "mainSourceFile" field. ...

The main source file is used as the root to access the whole package. This is important for dependency based building, such as with RDMD and for special build kinds, such as for a future unit test command. This also improves the robustness of "dub build --rdmd".

Main source files are automatically inferred as follows, if not explicitly given:
 1. search first in "source/", followed by "src/"
 2. take the first match of ("app.d", "main.d", "<pkgname>/main.d", "<pkgname>/<pkgname.d>") as the main file for the automatic "application" configuration
 3. take the first match of ("<pkgname>/all.d", "<pkgname>/package.d", "<pkgname>/<pkgname>.d") as the main file for the automatic "library" configuration

Don't emit -fPIC for DMD on Windows. Fixes #166.

Import and string import files are now added to generated VisualD projects and "dub describe".

Support excluding paths using glob matching.

Remove dub.internal.std.process compatibility code as it doesn't support browse() and the compile status on older DMD versions isn't tracked anyway.

Issue -shared and -fPIC when building shared libraries with DMD. Fixes #138.

Fix handling of lib flags on Windows for GDC/LDC.

fix gdc/ldc build options

Fix "-w" to be the default warnings mode again.

Properly escape arguments in GDC response files. Fixes #125.

Move dub.utils to dub.internal.utils and update copyright dates.

Let the individual compiler classes handle passing arguments to the compiler. Fixes #86.

Change BuildOptions.init from "debug_" to the new "none" to fix bogus -debug flags during compilation. ...

Also fix formatting and enable the warning about using --debug=xxx compiled flags directly.

Add -shared flag for DMD when building dynamic libraries.

Generalize common compiler switches in the form of a BuildOptions enum. ...

Related changes:
 - translation of DMD compiler switches to other compilers is generalized
 - application of build requirements is generalized
 - added support for debug versions
 - supporting almost all compiler settings for generated VisualD projects now

Improve adherence to code conventions.

Fix building of libraries with no explicit target type set. See #87.

Ignore import libraries when building a static library. Fixes #91.

Add "workingDirectory" build setting to change the working directory from which the final executable will be run. Fixes #84.

Avoid bogus warnings about non-recommended dflags.
