# Author:   David Rebatto (david.rebatto@mi.infn.it)
#
# Revision history:
#     8-Apr-2004: Original release
#    28-Apr-2004: Patched to handle arguments with spaces within (F. Prelz)
#                 -d debug option added (print the wrapper to stderr without submitting)
#    10-May-2004: Patched to handle environment with spaces, commas and equals
#    13-May-2004: Added cleanup of temporary file when successfully submitted
#    18-May-2004: Search job by name in log file (instead of searching by jobid)
#     8-Jul-2004: Try a chmod u+x on the file shipped as executable
#                 -w option added (cd into submission directory)
#    21-Sep-2004: -q option added (queue selection)
#    29-Sep-2004: -g option added (gianduiotto selection) and job_ID=job_ID_log
#    13-Jan-2005: -n option added (MPI job selection) and changed prelz@mi.infn.it with
#                    blahp_sink@mi.infn.it
#     4-Mar-2005: Dgas(gianduia) removed. Proxy renewal stuff added (-r -p -l flags)
#     3-May-2005: Added support for Blah Log Parser daemon (using the lsf_BLParser flag)
#    31-May-2005: Separated job's standard streams from wrapper's ones
#    26-Jul-2007: Restructured to use common shell functions.
# 
#
# Description:
#   Submission script for LSF, to be invoked by blahpd server.
#   Usage:
#     lsf_submit.sh -c <command> [-i <stdin>] [-o <stdout>] [-e <stderr>] [-w working dir] [-- command's arguments]
