# This is the Meteor install script!
#
# Are you looking at this in your web browser, and would like to install Meteor?
#
# MAC AND LINUX:
#   Just open up your terminal and type:
#
#     curl https://install.meteor.com/ | sh
#
#   Meteor currently supports:
#    - Mac: OS X 10.7 and above
#    - Linux: x86 and x86_64 systems
#
# WINDOWS:
#   Download the Windows installer from https://install.meteor.com/windows
#
#   Meteor currently supports Windows 7, Windows 8.1, Windows Server 2008,
#   and Windows Server 2012.

# We wrap this whole script in a function, so that we won't execute
# until the entire script is downloaded.
# That's good because it prevents our output overlapping with curl's.
# It also means that we can't run a partially downloaded script.
# We don't indent because it would be really confusing with the heredocs.

# This always does a clean install of the latest version of Meteor into your
# ~/.meteor, replacing whatever is already there. (~/.meteor is only a cache of
# packages and package metadata; no personal persistent data is stored there.)

# Now, on to the actual installer!

## NOTE sh NOT bash. This script should be POSIX sh only, since we don't
## know what shell the user has. Debian uses 'dash' for 'sh', for
## example.

Couldn't write the launcher script. Please either:

  (1) Run the following as root:
        cp "$LAUNCHER" /usr/bin/meteor
  (2) Add "\$HOME/.meteor" to your path, or
  (3) Rerun this command to try again.

Then to get started, take a look at 'meteor --help' or see the docs at
docs.meteor.com.

Now you need to do one of the following:
