PEINTURE SUR SOURCES (UN TRUC QUI FAIT DE LA COLORATION SYNTAXIQUE)

<?php
/*
Ce fichier permet de colorer des codes sources ou des fichiers poss&#65533;ant un formatage particulier :

Cette coloration synthaxique g&#65533;e les fichiers :
	-C
	-C++
	-PHP
	-SQL
	-XUL
	-CSS
	-HTML
	-XML
	-BAS
	-les fichiers de conf (ini)
	-javascript
	-povray
	-python
	-java

Faite dans le but de simplifier la lecture des sources sur mon blog,
r&#65533;tilis&#65533; ensuite pour le gestionnaire de past.
