/**
 * @file streamerinfo-from-raw.C
 * @brief Extract the streamer info for a raw file and AliRoot version
 *
 * This macro generates the streamer info for all objects in the HLTOUT
 * payload of the specified raw file. The AliRoot version of the when
 * running this macro needs to be the same as the HLTOUT payload was
 * generatted with.
 *
 * The macro has two optional parameters:
 * - filename:  default 'raw://'
 * - OCDB URI:  default 'raw.root'
 *
 * If either file or URI refers to the GRID, the macro connects to alien.
 * Make sure that ROOT is compiled with ALIEN support and that the required
 * alien API libraries can be loaded.
 *
 * You can run this macro with defaults using the following shell command:
 * @code
 *   > aliroot -b -q $ALICE_ROOT/HLT/rec/streamerinfo-from-raw.C
 * @endcode
 * With a raw file from the GRID
 * @code
 *   > aliroot -b -q streamerinfo-from-raw.C'("alien:///alice/data/2009/LHC09d/000102925/raw/09000102925035.10.root")'
 * @endcode
 *
 * Streamer info is stored in a TObjArray wrapped into an AliCDBEntry
 * object, and stored to HLT.StreamerInfo.root. This file can be used
 * directly as OCDB object, it just needs to be renamed.
