+<#
+.SYNOPSIS
+Executes KoreBuild commands.
+
+.DESCRIPTION
+Downloads korebuild if required. Then executes the KoreBuild command. To see available commands, execute with `-Command help`.
+
+.PARAMETER Command
+The KoreBuild command to run.
+
+.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 Reinstall
+Re-installs KoreBuild
+
+.PARAMETER ConfigFile
+The path to the configuration file that stores values. Defaults to korebuild.json.
+
+.PARAMETER ToolsSourceSuffix
+The Suffix to append to the end of the ToolsSource. Useful for query strings in blob stores.
+
+.PARAMETER CI
+Sets up CI specific settings and variables.
+
+.PARAMETER Arguments
+Arguments to be passed to the command
+
+.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 $ConfigFile is expected to be an JSON file. It is optional, and the configuration values in it are optional as well. Any options set
+in the file are overridden by command line parameters.
+
+.EXAMPLE
+Example config file:
+```json
+{
+  "$schema": "https://raw.githubusercontent.com/aspnet/BuildTools/master/tools/korebuild.schema.json",
+  "channel": "master",
+  "toolsSource": "https://aspnetcore.blob.core.windows.net/buildtools"

-            In general, we want the Node child processes to be terminated as soon as the parent .NET processes exit,
-            because we have no further use for them. If the .NET process shuts down gracefully, it will run its
-            finalizers, one of which (in OutOfProcessNodeInstance.cs) will kill its associated Node process immediately.
-            
-            But if the .NET process is terminated forcefully (e.g., on Linux/OSX with 'kill -9'), then it won't have
-            any opportunity to shut down its child processes, and by default they will keep running. In this case, it's
-            up to the child process to detect this has happened and terminate itself.
-            
-            There are many possible approaches to detecting when a parent process has exited, most of which behave
-            differently between Windows and Linux/OS X:
-            
-             - On Windows, the parent process can mark its child as being a 'job' that should auto-terminate when
-               the parent does (http://stackoverflow.com/a/4657392). Not cross-platform.
-             - The child Node process can get a callback when the parent disconnects (process.on('disconnect', ...)).
-               But despite http://stackoverflow.com/a/16487966, no callback fires in any case I've tested (Windows / OS X).
-             - The child Node process can get a callback when its stdin/stdout are disconnected, as described at
-               http://stackoverflow.com/a/15693934. This works well on OS X, but calling stdout.resume() on Windows
-               causes the process to terminate prematurely.
-             - I don't know why, but on Windows, it's enough to invoke process.stdin.resume(). For some reason this causes
-               the child Node process to exit as soon as the parent one does, but I don't see this documented anywhere.
-             - You can poll to see if the parent process, or your stdin/stdout connection to it, is gone
-               - You can directly pass a parent process PID to the child, and then have the child poll to see if it's
-                 still running (e.g., using process.kill(pid, 0), which doesn't kill it but just tests whether it exists,
-                 as per https://nodejs.org/api/process.html#process_process_kill_pid_signal)
-               - Or, on each poll, you can try writing to process.stdout. If the parent has died, then this will throw.
-                 However I don't see this documented anywhere. It would be nice if you could just poll for whether or not
-                 process.stdout is still connected (without actually writing to it) but I haven't found any property whose
-                 value changes until you actually try to write to it.
-            
-            Of these, the only cross-platform approach that is actually documented as a valid strategy is simply polling
-            to check whether the parent PID is still running. So that's what we do here.

+In general, we want the Node child processes to be terminated as soon as the parent .NET processes exit,
+because we have no further use for them. If the .NET process shuts down gracefully, it will run its
+finalizers, one of which (in OutOfProcessNodeInstance.cs) will kill its associated Node process immediately.
+
+But if the .NET process is terminated forcefully (e.g., on Linux/OSX with 'kill -9'), then it won't have
+any opportunity to shut down its child processes, and by default they will keep running. In this case, it's
+up to the child process to detect this has happened and terminate itself.
+
+There are many possible approaches to detecting when a parent process has exited, most of which behave
+differently between Windows and Linux/OS X:
+
+ - On Windows, the parent process can mark its child as being a 'job' that should auto-terminate when
+   the parent does (http://stackoverflow.com/a/4657392). Not cross-platform.
+ - The child Node process can get a callback when the parent disconnects (process.on('disconnect', ...)).
+   But despite http://stackoverflow.com/a/16487966, no callback fires in any case I've tested (Windows / OS X).
+ - The child Node process can get a callback when its stdin/stdout are disconnected, as described at
+   http://stackoverflow.com/a/15693934. This works well on OS X, but calling stdout.resume() on Windows
+   causes the process to terminate prematurely.
+ - I don't know why, but on Windows, it's enough to invoke process.stdin.resume(). For some reason this causes
+   the child Node process to exit as soon as the parent one does, but I don't see this documented anywhere.
+ - You can poll to see if the parent process, or your stdin/stdout connection to it, is gone
+   - You can directly pass a parent process PID to the child, and then have the child poll to see if it's
+     still running (e.g., using process.kill(pid, 0), which doesn't kill it but just tests whether it exists,
+     as per https://nodejs.org/api/process.html#process_process_kill_pid_signal)
+   - Or, on each poll, you can try writing to process.stdout. If the parent has died, then this will throw.
+     However I don't see this documented anywhere. It would be nice if you could just poll for whether or not
+     process.stdout is still connected (without actually writing to it) but I haven't found any property whose
+     value changes until you actually try to write to it.
+
+Of these, the only cross-platform approach that is actually documented as a valid strategy is simply polling
+to check whether the parent PID is still running. So that's what we do here.
