 * @file recraw-local.C
 * @brief Run reconstruction of raw data locally
 *
 * <pre>
 * Usage: aliroot -b -q -l \
 *     recraw-local.C'("file", "cdb", minEvent, maxEvent, modules)'
 *
 * Examples:
 *     recraw-local.C'("alien:///alice/data/2009/.../....root")' 
 *     recraw-local.C'("raw://run12345")'
 *     recraw-local.C'("raw://run12345", minEvent, MaxEvent)'
 *     recraw-local.C'("raw.root", "local://$PWD", minEvent, MaxEvent)'
 *
 * Defaults
 *     cdb="raw://"  -> take OCDB from GRID
 *     minEvent=-1   -> no lower event selection
 *     maxEvent=-1   -> no upper event selection
 *     modules="ALL" -> all modules
 *     hltOption="loglevel=0x7c" -> logging level info and above
 *
 * </pre>
 *
 * The input file can be a file on the grid, indicated by the tag
 * 'alien://' indicates. By default also the OCDB is set to the GRID.
 * If either the file or the OCDB is taken from the GRID, the macros
 * connects to the Grid in the beginning.
 *
 * Input files can be specified via te run number when using the tag
 * 'raw://' followed by the string 'run12345' where the number needs
 * to be adjusted.
 *
 * As for the OCDB it is always a good idea to use the OCDB from the
 * Grid as this will contain all the necessary objects and the latest
 * calibration. The special URI 'raw://' is most advisable as it selects
 * the storage automatically from the run number. Other options are e.g.
 * - "alien://folder=/alice/data/2010/OCDB"
 * - "local://$ALICE_ROOT/OCDB"
 *
 * Re-running the HLT reconstruction
 * By specifying the hlt options, the HLT chain can be re-run instead
 * of just extracting the online result. E.g. the following options
 * specify to ignore the HLTOUT payload and run the two chains defined
 * in the agents. The translation of the online configuration into
 * an HLT offline chain is under development.
 * <pre>
 *   ignore-hltout chains=GLOBAL-esd-converter,TPC-clusters
 * <pre>
 *
 * Note: You need a valid GRID token, use 'alien-token-init' of your
 * alien installation.
