// An assimilator that runs a script to handle completed jobs,
// so that you can do assimilation in Python, PHP, Perl, bash, etc.
//
// cmdline args to this program:
// --script "scriptname arg1 ... argn"
//
// The script assimilates a completed job.
//
// arg1 ... argn represent cmdline args to be passed to the script.
// the options are:
//
// files list of output files of the job's canonical result
// wu_id workunit ID
// result_id ID of the canonical result
// runtime runtime of the canonical result
//
// if no args are specified, the script is invoked as
// scriptname wu_id files
//
// If the workunit has no canonical result (i.e. it failed)
// the script is invoked as
// scriptname --error N wu_id
// where N is an integer encoding the reasons for the job's failure
// (see WU_ERROR_* in html/inc/common_defs.inc)
