/** @mainpage Documentation for the mumudvb project
* @section introduction
* Mumudvb is a program that can redistribute streams from DVB on a network using
* multicasting or HTTP unicast. It is able to multicast a whole DVB transponder by assigning
* each channel to a different multicast IP.
*
* @section Main features
* Stream channels from a transponder on different multicast IPs
* The program can rewrite the PAT Pid in order to announce only present channels (useful for some set-top boxes)
* Support for scrambled channels (if you don't have a CAM you can use sasc-ng, but check if it's allowed in you country)
* Support for autoconfiguration
* Generation of SAP announces
*@section files
* mumudvb.h header containing global information
*
* autoconf.c autoconf.h code related to autoconfiguration
*
* cam.c cam.h : code related to the support of scrambled channels
*
* crc32.c : the crc32 table
*
* dvb.c dvb.h functions related to the DVB card : oppening filters, file descriptors etc
*
* log.c logging functions
*
* pat_rewrite.c rewrite.h : the functions associated with the rewrite of the PAT pid
*
* sdt_rewrite.c rewrite.h : the functions associated with the rewrite of the SDT pid
*
* sap.c sap.h : sap announces
*
* ts.c ts.h : function related to the MPEG-TS parsing
*
* tune.c tune.h : tuning of the dvb card
*
* network.c network.h : networking ie openning sockets, sending packets
*
* unicast_http.c unicast_http.h : HTTP unicast
