XeTeX (pronounced /ˈ ziːtɛ x/ or /ˈziːtɛ χ/, though English lacks /x/ or /χ/) is a TeX typesetting engine using Unicode and supporting modern font technologies such as OpenType or Apple Advanced Typography. It is written and maintained by Jonathan Kew and distributed under the X11 free software license.

Background: Some familiarity with TEX, LATEX, and XETEX is to be gained first.

1.1 Purpose:

TEX and LATEX do not allow direct coding of texts in non-Roman scripts and languages, and have no native support for Unicode. XETEX addresses this. This is a Web 2.0 API that allows web programmers to create XETEX web applications. The applications themselves will allow users to process documents. It supports languages like English, Tamil and Hindi, the fonts should be True-Type/Open Type/Unicode, and allows for highlighting, italics, easy rescaling, etc., and also it allow the production of camera-ready documents suitable for printing and binding.

2. System Requirements:

Server Side:

• Apache

• PHP

• Xetex compiler from TeXLive

Client side

• Web browser like IE 6.0 and above or Mozilla firefox

• Flash player plugin

3. Installation
