+   This script automates the experiment setup process for the global workflow.
+   Options are also available to update submodules, build the workflow (with
+   specific build flags), specicy which YAMLs and YAML directory to run, and
+   whether to automatically update your crontab.
+
+   Usage: generage_experiments.sh [OPTIONS] /path/to/RUNTESTS
+
+    -H Root directory of the global workflow.
+       If not specified, then the directory is assumed to be one parent
+       directory up from this script's residing directory.
+
+    -b Run build_all.sh with default flags
+       (build the UFS, UPP, UFS_Utils, and GFS-utils only
+
+    -B "build flags"
+       Run build_all.sh with the build specified flags.  Refer to
+       build_all.sh -h for a list of valid flags.
+       NOTE: the list of build flags MUST be in quotes.
+
+    -u Update submodules before building and/or generating experiments.
+
+    -y "list of YAMLs to run"
+       If this option is not specified, the default case (C48_ATM) will be
+       run.  This option is overidden by -G or -E (see below).
+       Example: -y "C48_ATM C48_S2SW C96C48_hybatmDA"
+
+    -Y /path/to/directory/with/YAMLs
+       If this option is not specified, then the \${HOMEgfs}/ci/cases/pr
+       directory is used.
+
+    -G Run all valid GFS cases in the specified YAML directory.
+       If -b is specified, then "-g -u" (build the GSI and GDASApp)
+       will be passed to build_all.sh unless -B is also specified.
+       Note that these builds are disabled on some systems, which
+       will result in a warning from build_all.sh.
+
+    -E Run all valid GEFS cases in the specified YAML directory.
+       If -b is specified, then "-w" will be passed to build_all.sh
+          unless -B is also specified.
+
+    -S (Not yet supported!)
+       Run all valid SFS cases in the specified YAML directory.
+
+    NOTES:
+         - Only one of -G -E or -S may be specified
+         - Valid cases are determined by the experiment:system key as
+           well as the skip_ci_on_hosts list in each YAML.
+
+    -A "HPC account name"  Set the HPC account name.
+       If this is not set, the default in
+       \$HOMEgfs/ci/platform/config.\$machine
+       will be used.
+
+    -c Append the chosen set of tests to your existing crontab
+       If this option is not chosen, the new entries that would have been
+       written to your crontab will be printed to stdout.
+       NOTES:
+          - This option is not supported on Gaea.  Instead, the output will
+            need to be written to scrontab manually.
+          - For Orion/Hercules, this option will not work unless run on
+            the [orion|hercules]-login-1 head node.
+
+    -e "your@email.com" Email address to place in the crontab.
+       If this option is not specified, then the existing email address in
+       the crontab will be preserved.
+
+    -v Verbose mode.  Prints output of all commands to stdout.
+
+    -V Very verbose mode.  Passes -v to all commands and prints to stdout.
+
+    -d Debug mode.  Same as -V but also enables logging (set -x).
+
+    -h Display this message.
