# Script
#     foamCloneCase
#
# Description
#     Create a new case directory that includes time, system and constant
#     directories from a source case.
#     The time directory is the first time directory by default
#     - requires foamListTimes v2.3.x and newer

    cat<<USAGE

Usage: ${0##*/} [OPTION] <source case> <target name>
options:
  -help          print the usage
  -latestTime    clone the latest time directory
  -no-orig       do not copy 0.orig directory
  -no-scripts    do not copy shell scripts
  -template      search for source case directory in template directory paths

Create a new <targetCase> case directory that includes time, system and constant
directories, and shell scripts, of <sourceCase> directory.
The time directory is the first time directory by default.  If no time directory
exists, or it is 0, an exitsting 0.orig directory is copied by default.

Template directory paths are:
