During development process or for checking a live install, and if you don't want to ftp to your site, you can use this block to submit a portion of code directly into your pages. With this you can obtain, by example, a phpinfo() more quickly than ever, or check variables values, or even use advanced commands, include portion of script ...
There is no security checking and no code cleaning, so be careful, you can do whatever you want but it's the aim.
This block supports l10n and is packaged with en/fr. Feel free to send me your translation, I'll include it asap.
