Typo3 is a system of really impressive handling of contents opensource. Using this program we can create incredibly powerful Web sites, using its interface - very consistent and expandable by we ourself. One is based on Apache+Php+MySql and it is used by great amount of important pages… (they are possible to be consulted in its Web).
To the being totally opensource we can modify it so that one adapts exactly to its needs, although has a system of plugins that allows to make almost any thing.
