+# queue.pl has the same functionality as run.pl, except that

+# This version of queue.pl uses the task array functionality
+# of the grid engine. Note: it's different from the queue.pl
+# in the s4 and earlier scripts.
+
+# The script now supports configuring the queue system using a config file
+# (default in conf/queue.conf; but can be passed specified with --config option)
+# and a set of command line options.
+# The current script handles:
+# 1) Normal configuration arguments
+# For e.g. a command line option of "--gpu 1" could be converted into the option
+# "-q g.q -l gpu=1" to qsub. How the CLI option is handled is determined by a
+# line in the config file like
+# gpu=* -q g.q -l gpu=$0
+# $0 here in the line is replaced with the argument read from the CLI and the
+# resulting string is passed to qsub.
+# 2) Special arguments to options such as
+# gpu=0
+# If --gpu 0 is given in the command line, then no special "-q" is given.
+# 3) Default argument
+# default gpu=0
+# If --gpu option is not passed in the command line, then the script behaves as
+# if --gpu 0 was passed since 0 is specified as the default argument for that
+# option
+# 4) Arbitrary options and arguments.
+# Any command line option starting with '--' and its argument would be handled
+# as long as its defined in the config file.
+# 5) Default behavior
+# If the config file that is passed using is not readable, then the script
+# behaves as if the queue has the following config file:
+# $ cat conf/queue.conf
+# # Default configuration
+# command qsub -v PATH -cwd -S /bin/bash -j y -l arch=*64*

+# the bash shell, and putting the standard error and output into some.log.
+# To run parallel jobs (backgrounded on the host machine), you can do (e.g.)
+# run.pl JOB=1:4 some.JOB.log a b c JOB is like running the command a b c JOB
+# and putting it in some.JOB.log, for each one. [Note: JOB can be any identifier].
+# If any of the jobs fails, this script will fail.
+
+# A typical example is:
+# run.pl some.log my-prog "--opt=foo bar" foo \| other-prog baz
+# and run.pl will run something like:
+# ( my-prog '--opt=foo bar' foo | other-prog baz ) >& some.log
+#
+# Basically it takes the command-line arguments, quotes them
+# as necessary to preserve spaces, and evaluates them with bash.
