=head1 NAME

    init_pipeline.pl

=head1 SYNOPSIS

    init_pipeline.pl <config_module_or_filename> [-help | [-analysis_topup | -job_topup] <options_for_this_particular_pipeline>]

=head1 DESCRIPTION

    init_pipeline.pl is a generic script that is used to create+setup=initialize eHive pipelines from PipeConfig configuration modules.

=head1 USAGE EXAMPLES

        # get this help message:
    init_pipeline.pl

        # initialize a generic eHive pipeline:
    init_pipeline.pl Bio::EnsEMBL::Hive::PipeConfig::HiveGeneric_conf -password <yourpassword>

        # see what command line options are available when initializing long multiplication example pipeline
        #   (assuming your current directory is ensembl-hive/modules/Bio/EnsEMBL/Hive) :
    init_pipeline.pl PipeConfig/LongMult_conf -help

        # initialize the long multiplicaton pipeline by supplying not only mandatory but also optional data:
        #   (assuming your current directory is ensembl-hive/modules/Bio/EnsEMBL/Hive/PipeConfig) :
    init_pipeline.pl LongMult_conf -password <yourpassword> -first_mult 375857335 -second_mult 1111333355556666 

=head1 OPTIONS

    -help            :   Gets this help message and exits

    -analysis_topup  :   A special initialization mode when (1) pipeline_create_commands are switched off and (2) only newly defined analyses are added to the database
                         This mode is only useful in the process of putting together a new pipeline.

    -job_topup       :   Another special initialization mode when only jobs are created - no other structural changes to the pipeline are acted upon.

    -hive_force_init :   If set to 1, forces the (re)creation of the hive database even if a previous version of it is present in the server.
