 If you're planning to submit a pull request, and if it's more than a trivial fix (for example, for a typo), it's usually a good idea first to file an issue describing what you're proposing to do and how it will work. Then you can find out if it's likely that such a pull request will be accepted, and how it fits into wider ongoing plans.

-.DESCRIPTION
-Downloads korebuild if required. Then builds the repository.
-
-.PARAMETER Path
-The folder to build. Defaults to the folder containing this script.
-
-.PARAMETER Channel
-The channel of KoreBuild to download. Overrides the value from the config file.
-
-.PARAMETER DotNetHome
-The directory where .NET Core tools will be stored.
-
-.PARAMETER ToolsSource
-The base url where build tools can be downloaded. Overrides the value from the config file.
-
-.PARAMETER Update
-Updates KoreBuild to the latest version even if a lock file is present.
-
-.PARAMETER ConfigFile
-The path to the configuration file that stores values. Defaults to version.xml.
-
-.PARAMETER MSBuildArgs
-Arguments to be passed to MSBuild
-
-.NOTES
-This function will create a file $PSScriptRoot/korebuild-lock.txt. This lock file can be committed to source, but does not have to be.
-When the lockfile is not present, KoreBuild will create one using latest available version from $Channel.
-
-The $ConfigFile is expected to be an XML file. It is optional, and the configuration values in it are optional as well.
-
-.EXAMPLE
-Example config file:
-```xml
-<!-- version.xml -->
-<Project>
-  <PropertyGroup>
-    <KoreBuildChannel>dev</KoreBuildChannel>
-    <KoreBuildToolsSource>https://aspnetcore.blob.core.windows.net/buildtools</KoreBuildToolsSource>
-  </PropertyGroup>
-</Project>

-// On Windows, Node (still as of v8.1.3) has an issue whereby, when locating JavaScript modules
-// on disk, it walks up the directory hierarchy to the disk root, testing whether each directory
-// is a symlink or not. This fails with an exception if the process doesn't have permission to
-// read those directories. This is a problem when hosting in full IIS, because in typical cases
-// the process does not have read permission for higher-level directories.
-//
-// NodeServices itself works around this by injecting a patched version of Node's 'lstat' API that
-// suppresses these irrelevant errors during module loads. This covers most scenarios, but isn't
-// enough to make Webpack dev middleware work, because typical Webpack configs use loaders such as
-// 'awesome-typescript-loader', which works by forking a child process to do some of its work. The
-// child process does not get the patched 'lstat', and hence fails. It's an especially bad failure,
-// because the Webpack compiler doesn't even surface the exception - it just never completes the
-// compilation process, causing the application to hang indefinitely.
-//
-// Additionally, Webpack dev middleware will want to write its output to disk, which is also going
-// to fail in a typical IIS process, because you won't have 'write' permission to the app dir by
-// default. We have to actually write the build output to disk (and not purely keep it in the in-
-// memory file system) because the server-side prerendering Node instance is a separate process
-// that only knows about code changes when it sees the compiled files on disk change.
-//
-// In the future, we'll hopefully get Node to fix its underlying issue, and figure out whether VS
-// could give 'write' access to the app dir when launching sites in IIS. But until then, disable
-// Webpack dev middleware if we detect the server process doesn't have the necessary permissions.
