# Command-line options
# ==============================================================================
#
# --version
# Use the --version option to install a special version for installation. default is latest, for example:
#
#  $ sudo bash install.sh --version "0.8.25"
#
# --port <9000>
# Use the --port option to set Websoft9 cosole port. default is 9000, for example:
#
#   $ sudo bash install.sh --port 9001
#
# --channel <release|dev>
# Use the --channel option to install a release(production) or dev distribution. default is release, for example:
#
#  $ sudo bash install.sh --channel release
#
# --path
# Use the --path option to for installation path for example:
#
#  $ sudo bash install.sh --path "/data/websoft9/source"
#
# --devto
# Use the --devto option to developer mode, devto is the developer code path, for example:
#
#  $ sudo bash install.sh --devto "/data/dev/mycode"
