This website is a set of practical, detailed tutorials for people who want to learn Objective CAML (often known as just "OCaml").
OCaml is a fast, concise and powerful language for application development - but I assume you already knew that, and I also assume you've managed to install it. If not, you can find out more at the main OCaml webpages or at the OCaml Alliance's getting started area.
Foreign language versions are:
- Deutsche Version (German version)
- Version française (French version)
- Versione italiana (Italian version)
- 日本語版 (Japanese version)
- 한국어판 (Korean version)
- 简体中文版(Simplified Chinese version)(in progress)
