3 # SliTaz Helper for SHell CGI scripts - See httphelper function
4 #
5 # This helper is used in TazPanel, Pizza and other SliTaz CGI tools and
6 # services. The goal is to maintain it according to the needs of the
7 # project and Busybox httpd server applet since it is used for URL
8 # [en|de]coding.
