Build.bat

:: UT99 Build System For Windows
:: 
:: Expects to have been placed in the root directory of the
:: package you want to build.
:: 
:: Options:
::   BuildDir <directory> - Manually specify the root directory of the package
::     Example: C:\UT99\MyPackage\Build\Build.bat BuildDir "C:\UT99\MyPackage\"
::   NoInt - Do not automatically generate a .int for the package
::   NoUz - Do not automatically generate a .u.uz for the package
::   Silent - Suppresses compatibility warnings, automatically resolves them
::   NoBind - Prevents binding native functions to C++ implementations, useful when adding new natives
::   Verbose - Can be used multiple times. More verbose -> More output from script
:: 
:: Dependencies:
::   There is a way to specify dependencies.
::   First, you need to add them to the list of dependencies
::    in BuildSettings.bat, which can be found next to this
::    file.
::   Second, you need to add a new folder under
::    Build/Dependencies/ with the name of the dependency.
::   Third, place inside it all resources for the dependency
::    in the same folder structure the game expects packages
::    to be in. That means .u files need to be inside a
::    System subfolder, .utx in a Textures subfolder, etc.
::   Example:
::    Lets say you have a package called MyPackage which
::    depends on a package called MyDependency. Here is what
::    the (simplified) folder structure should look like:
::      C:\UT99\MyPackage\
::      ├─Build\
::      │ └─Dependencies\
::      │   └─MyDependency\
::      │     ├─System\
::      │     │ └─MyDependency.u
::      │     └─Textures\
::      │       └─MyDependencyTex.utx
::      ├─Classes\
::      │ └─MyClass.uc
::      ├─Build.bat
::      └─BuildSettings.bat
:: 
:: A non-exhaustive list of reason you depend on a package:
::   - When you extend a class of another package
::      Example:
::       class MyClass extends MyDependency.CoolBaseClass;
::   - When you declare a variable/member of a type from
::     your dependency within one of your classes
::      Example:
::       var MyDependency.CoolClass MyVar;
::   - When you cast to a class from another package
::      Example:
::       MyVar = CoolClass(SomeActor);
::   - When you refer to an object from a dependency
::      Examples:
::       SomeClass = class'MyDependency.CoolClass';
::       SomeTex = Texture'MyDependency.CoolTexture';
::       SomeMesh = LodMesh'MyDependency.CoolMesh';
:: 
:: Be careful about what packages you depend on.
:: - Server admins need to install them together with your
::    package, which also means they need to redirect them
::    for people to download. More work for server admins
::    slows adoption of your package by them.
:: - Packages without obvious versioning might have multiple
::    different and incompatible versions using the same
::    name and being depended on by various other mods.
:: - Server admins might run into problems where your
::    package depends on version 2 of MyDependency, but
::    another package the server admin wants to use depends
::    on version 1 of MyDependency, which cant be resolved.
:: - As a consequence, make sure every package you release
::    has version information in the name, especially if you
::    expect to be depended on by someone else.
::
:: PostBuildHook:
::   PostBuildHook.bat is executed after a successful build
::    if it exists next to this file. This is intended for
::    use with automation, like, for example, updating a
::    server with the shiny new version of MyPackage that
::    was just built.
::   For this reason PostBuildHook.bat should not be
::    archived in version control or shared with others.
::
::   If the NoBind option is specified, PostBuildHook will
::    never be called because NoBind is an intermediary step
::    towards the final package.
