*XGAP* stands for *__X__ml -- __G__enerador de __AP__licaciones*.

XGAP was born in 2003 at the http://www.unicen.edu.ar/[UNICEN University] as a
tool for creating web applications for the intranet.

At first, the platform was PHP and PostgreSQL database. Nowadays XGAP-generated
applications work with http://www.postgresql.org/[PostgreSQL] or
http://www.oracle.com/us/products/database/index.html[Oracle] databases, but
all http://adodb.sourceforge.net/[ADOdb] databases can be supported.

The primary goal of XGAP is to assist the programmer in the repetitive and
common coding tasks. That's why XGAP concentrates more in specifying an
application than in programming it. You program a web application using XGAP by
creating a set of XML files that describe the application. Those XML files are
taken by the generator and the PHP files are created by means of XSLT sheets.
The application is installed and redirected once the process is completed so as
you can start using it.

XGAP solves these tasks:

* Creation of listings, add/remove/modify forms for the tables of the database,
  master-detail forms, charts
* Pop-up selection listings
* Automatic paging
* Basic/Advanced search filters
* Automatic report generators (ODT, PDF, RTF, CSV)
* Automatic data type detection from the database
* Automatic detection of required fields
* Client and/or server-side validation of user input
* HTML editor included
* Security (users, roles, permissions)
* Code extension points, useful to solve custom application needs and business
  rules
* And many more...

WARNING: Right now XGAP is 'not' internationalized or localized. All
messages are written in Spanish and assume Argentinian locale.
