• The directory src contains the Visual Studio solution with the actual source code.
• The directory lib contains pre-compiled 3rd party libraries which are not available via NuGet.
• The directory doc contains scripts for generating source code and developer documentation.
• The directory modeling contains UML and other diagrams.
• The directory installer contains scripts for creating a Windows installer.
• The directory bundled contains a portable GnuPG distribution (Windows only) and an external solver (all platforms).
• The directory build contains the results of various compilation processes. It is created on first usage. It can contain the following subdirectories:
  • Backend: Contains the libraries forming the Zero Install Backend.
  • Frontend: Contains the executables for the Zero Install Frontend plus all required libraries (including the Backend).
  • Tools: Contains the executables for Zero Install Tools such as the Feed Editor plus all required libraries (including the Backend).
  • Installer: Contains the generated installers.
  • Documentation: Contains the generated source code documentation.
• The directory feeds contains local Zero Install feeds referencing the contents of the build directory. They can be registered with 0install add-feed in order to replace the online versions of Zero Install and its tools with your local builds.

VERSION and VERSION_UPDATER contain the version numbers used by build scripts. Keep in sync with the version numbers in src/AssemblyInfo.Global.cs and src/Updater/AssemblyInfo.Updater.cs!

The external solver (required) is not included in the repository. To get it run bundled/download-solver.ps1.

build.cmd will call build scripts in subdirectories to create a Zero Install for Windows installer in build/Frontend/Installer. Note: Please read installer/readme.txt aswell for information about required tools.

cleanup.cmd will delete any temporary files created by the build process or Visual Studio.

The external solver (required) is not included in the repository. To get it run bundled/download-solver.sh.

build.sh will perform a partial debug compilation using Mono's xbuild. A installer package will not be built.

cleanup.sh will delete any temporary files created by the xbuild build process.

test.sh will run the unit tests using the NUnit console runner. Note: You must perform a Debug build first (using MonoDevelop or src/build.sh) before you can run the unit tests.

• ZEROINSTALL_PORTABLE_BASE: Set by the C# code to to inform the Python code of Portable mode.
• ZEROINSTALL_EXTERNAL_FETCHER: Set by the C# code to make the Python code delegate downloading files back to the C# implementation.
• ZEROINSTALL_EXTERNAL_STORE: Set by the C# code to make the Python code delegate extracting archives back to the C# implementation.
