Description

If --version is present, print version information and exit. Otherwise <tool-arguments> should begin with the name of a ceylon tool or a list of comma-separated tool names which will be invoked one after the other with the same remaining command line arguments. The named tools are loaded and configured with the remaining command line arguments and control passes to those tools.

Options
--config=file

Specifies the configuration file to use for this tool. (default: ./.ceylon/config)
--cwd=dir

Specifies the current working directory for this tool. (default: the directory where the tool is run from)
--define=key>=<value, -D key>=<value

Set a system property
--distribution=version-or-url

Determines which Ceylon distribution will be used to run the command. Passing any version except the current (1.2.2) will result in a one-time download of the requested version from the official Ceylon website.
--no-pager

Do not pipe Ceylon tool output into a pager.
--paginate

Pipe all Ceylon tool output into less (or if set, $CEYLON_PAGER or $PAGER) if standard output is a terminal. This overrides the help.pager and defaults.pager configuration options (see the "Configuration Mechanism" section below).
--show-home

Outputs the value for CEYLON_HOME and exits.
--stacktraces

If an error propagates to the top level tool, print its stack trace.
--version, -v

Print version information and exit, ignoring all other options and arguments.

CONFIGURATION MECHANISM

Ceylon uses a simple text format to store customizations that are per repository and are per user. Such a configuration file may look like this:

#
# A '#' or ';' character indicates a comment.
#

; global settings
[defaults]
    encoding = utf8
    pager = false

; local repository
[repository "LOCAL"]
    url = ./modules

Various commands read from the configuration file and adjust their operation accordingly. See ceylon-config(1) for a list and more details about the configuration mechanism.
