## 4.3 Converting from other formats

Music can be entered also by importing it from other formats. This chapter documents the tools included in the distribution to do so. There are other tools that produce LilyPond input, for example GUI sequencers and XML converters. Refer to the website for more details.

These are separate programs from `lilypond` itself, and are run on the command line; see Command-line usage for more information. If you have MacOS 10.3 or 10.4 and you have trouble running some of these scripts, e.g. `convert-ly`, see MacOS X.

#### Known issues and warnings

We unfortunately do not have the resources to maintain these programs; please consider them “as-is”. Patches are appreciated, but bug reports will almost certainly not be resolved.
