INTRODUCTION

Roundcube Webmail is a browser-based multilingual IMAP client with an application-like user interface. It provides full functionality you expect from an email client, including MIME support, address book, folder management, message searching and spell checking. Roundcube Webmail is written in PHP and requires the MariaDB, MySQL, PostgreSQL or SQLite database. With its plugin API it is easily extendable and the user interface is fully customizable using skins.

The code designed to run on a webserver is mainly written in PHP and Javascript. It includes a custom framework with an IMAP library derived from [IlohaMail][iloha] and requires a set of external libraries (see composer.json and jsdeps.json files).
