## General options

  -e "COMMAND"                 Evaluates the given command (*)
  -h, --help                   Prints this message and exits
  -r "FILE"                    Requires the given files/patterns (*)
  -S SCRIPT                    Finds and executes the given script in \$PATH
  -pr "FILE"                   Requires the given files/patterns in parallel (*)
  -pa "PATH"                   Prepends the given path to Erlang code path (*)
  -pz "PATH"                   Appends the given path to Erlang code path (*)
  -v, --version                Prints Elixir version and exits

  --app APP                    Starts the given app and its dependencies (*)
  --erl "SWITCHES"             Switches to be passed down to Erlang (*)
  --eval "COMMAND"             Evaluates the given command, same as -e (*)
  --logger-otp-reports BOOL    Enables or disables OTP reporting
  --logger-sasl-reports BOOL   Enables or disables SASL reporting
  --no-halt                    Does not halt the Erlang VM after execution
  --werl                       Uses Erlang's Windows shell GUI (Windows only)

Options given after the .exs file or -- are passed down to the executed code.
Options can be passed to the Erlang runtime using \$ELIXIR_ERL_OPTIONS or --erl.

## Distribution options

The following options are related to node distribution.

  --cookie COOKIE              Sets a cookie for this distributed node
  --hidden                     Makes a hidden node
  --name NAME                  Makes and assigns a name to the distributed node
  --rpc-eval NODE "COMMAND"    Evaluates the given command on the given remote node (*)
  --sname NAME                 Makes and assigns a short name to the distributed node

## Release options

The following options are generally used under releases.

  --boot "FILE"                Uses the given FILE.boot to start the system
  --boot-var VAR "VALUE"       Makes \$VAR available as VALUE to FILE.boot (*)
  --erl-config "FILE"          Loads configuration in FILE.config written in Erlang (*)
  --pipe-to "PIPEDIR" "LOGDIR" Starts the Erlang VM as a named PIPEDIR and LOGDIR
  --vm-args "FILE"             Passes the contents in file as arguments to the VM

--pipe-to starts Elixir detached from console (Unix-like only).
It will attempt to create PIPEDIR and LOGDIR if they don't exist.
See run_erl to learn more. To reattach, run: to_erl PIPEDIR.

** Options marked with (*) can be given more than once.
