Description: lightweight HTTP server for static content
This package provides a simple web server for mostly static content,
with limited CGI support (GET requests only).
.
Example uses include giving HTTP access to the contents of an FTP
site, or exporting some files by quickly starting a web server
without any need to edit configuration files first.
Чот не догоняю, система самая базовая, откуда там прилетел веб сервер по зависимостям.
