# Initial revision
#
#
# Description:
# ------------
# PALM job manager works a file manager for PALM input files. It lists all jobs in
# the working directory and displays associated input and user code files, which
# can be opened directly from the interface. Also, it is possible to copy jobs and
# to create entire new sets of jobs based on a reference job.
# 
# Instructions:
# -------------
# 1) Start palm_jm either from mrungui or from shell by "nohup palm_jm&"
#
# To do:
# ------
# 1) Add display for the MONITORING and OUTPUT folder
# 2) Add zip function to export single or multiple jobs
# 3) Allow for copying INPUT files to a remote host
