NAME

       globus_gram_job_manager_script_interface - Job Manager Scheduler Interface The GRAM Job Manager interfaces with the job filesystems and
       scheduler through scheduler-specific Perl modules.

       GRAM provides several Perl modules which can be used to implement scheduler-specific interfaces to the GRAM Job Manager. These are:

       Globus::GRAM::Error
	   This module implements the GRAM error results as objects. Methods in this module will construct a GRAM error with the value matching
	   the values in the GRAM Protocol library. A scheduler-specific JobManager module may return one of these objects from its methods to
	   indicate errors to the Job Manager program.

       Globus::GRAM::JobState
	   This module defines the GRAM job state constants. A scheduler-specific JobManager module returns one of these values from its methods
	   to indicate the managed job's current state.

       Globus::GRAM::JobSignal
	   This module defines the GRAM job signal constant values. The Job Manager uses these values to communicate which signal is being invoked
	   in the manager's signal method.

       Globus::GRAM::JobManager
	   This module defines the actual implementatoin of the Job Manager scheduler interface. One writing a scheduler-specific GRAM interface
	   will create a subclass of this object which overrides the default implementation's methods.

       Globus::GRAM::JobDescription
	   This module mimics the RSL job description using perl syntax. The job manager passes an object of this type to the JobManager modules's
	   constructor. The job manager stores RSL and some configuration values in that JobDescription object. The manager accesses values stored
	   in the JobDescription by invoking methods containing the RSL attribute's name (example: $description->gram_my_job()). Method names are
	   handled as if they were based on the canonical RSL representation of the attribute name. For example, the gram_my_job may be
	   equivalently referred to as GramMyJob, grammyjob, or GRAM_My_Job.
