/** \mainpage libcaca Documentation

 \section intro Introduction

 \e libcaca is a graphics library that outputs text instead of pixels,
 so that it can work on older video cards or text terminals. It is not
 unlike the famous AAlib library. \e libcaca can use almost any virtual
 terminal to work, thus it should work on all Unix systems (including
 Mac OS X) using either the S-Lang library or the ncurses library, on DOS
 using the conio library, and on Windows systems using the native Win32
 console, the conio library, or using S-Lang or ncurses (through Cygwin
 emulation). There is also a native X11 driver, and an OpenGL driver
 (through freeglut) that does not require a text terminal. For machines
 without a screen, the raw driver can be used to send the output to another
 machine, using for instance cacaserver.

 \e libcaca is free software, released under the Do What the Fuck You
 Want to Public License. This ensures that no one, not even the \e libcaca
 developers, will ever have anything to say about what you do with the
 software. It used to be licensed under the GNU Lesser General Public
 License, but that was not free enough.
