Java launcher part for Minecraft.
It:
It does the following:
- Starts a process
- Waits for a launch script on stdin
- Consumes the launch script you feed it
- Proceeds with launch when it gets the `launcher` command
- Waits for a launch script on stdin.
- Consumes the launch script you feed it.
- Proceeds with launch when it gets the `launcher` command.
If "abort" is sent, the process will exit.
This means the process is essentially idle until the final command is sent. You can, for example, attach a profiler before you send it.
A `legacy` and `onesix` launchers are available.
The `standard` and `legacy` launchers are available.
- `standard` can handle launching any Minecraft version, at the cost of some extra features `legacy` enables (custom window icon and title).
- `legacy` is intended for use with Minecraft versions < 1.6 and is deprecated.
- `onesix` can handle launching any Minecraft version, at the cost of some extra features `legacy` enables (custom window icon and title).
