# Corrected "Former revisions" section
# 
# 2696 2017-12-14 17:12:51Z kanani
# Change in file header (GPL part)
#
# 2693 2017-12-13 12:33:49Z raasch
# replacement of variables given by {{<variable>}} in configuration file is now
# done in a more general way, variable names are written in small letters
# 
# 2670 2017-12-06 16:32:19Z raasch
# test printouts removed
# 
# 2669 2017-12-06 16:03:27Z raasch
# file attributes in .palm.iofiles restructured, "loc" attribute completely
# removed,
# wildcard (*) allowed in .palm.iofiles as file activation string for output
# files,
# informative messages in case of missing optional input files shortened
# bugfix: variable cycle explicitly interpreted with 10 as the number base
# 
# 2638 2017-11-23 12:44:23Z raasch
# use of wildcards in file connection statements enabled
# 
# 2605 2017-11-09 15:31:46Z raasch
# in case of remote jobs, input files with "job" or "jobopt" (new) attribute
# will not be sent with the job file any more, but copied into the
# SOURCES_FOR_RUN... folder on the remote host, before the job is submitted
# 
# 2600 2017-11-01 14:11:20Z raasch
# cycle numbers are made three digits wide
# 
# 2566 2017-10-20 08:50:47Z raasch
# execute command for combine_plot_fields added
# "TEMPDIR" renamed "tempdir"
# temporary working directory for local batch jobs is created immediately within
# the user's palmrun call, due to a requirement of the "grid engine" batch
# system, where the working directory is given with batch directive -wd and must
# already exist when the job is submitted,
# informative messages in non-trace mode reduced and partly reformatted
# 
# 2551 2017-10-18 07:25:11Z raasch
# TEMPDIR added as replacement string to be used in batch directives
# 
# 2512 2017-10-04 08:26:59Z raasch
# bugfix for determining cycle numbers of NetCDF input files
# 
# 2506 2017-09-29 08:30:37Z raasch
# option -V added to check for an existing SOURCES_FOR_RUN_... folder
# host configuration added to SOURCES_FOR_RUN_... folder name
# host_identifier renamed host_configuration
# option -W added to allow for job dependencies
# 
# 2501 2017-09-26 11:41:55Z raasch
# default value for number of cores (option -X) set to 1
# bugfix for mechanism which overwrites configuration file settings with values
# provided by palmrun options
# 
# 2499 2017-09-22 16:47:58Z kanani
# option -h named configuration identifier
