# Plex Linux Server download tool
# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
# This tool will download the latest version of Plex Media
# Server for Linux. It supports both the public versions
# as well as the PlexPass versions.
#
# PlexPass users:
# Either modify this file to add email and password OR create
# a separate .plexupdate file in your home directory with these
# values.
#
# Returns 0 on success
# 1 on error
# 2 if file already downloaded
# 3 if page layout has changed.
# 4 if download fails
# 5 if version already installed
#
# All other return values not documented.
#
# Call program with -h for available options
#
# Enjoy!
#
# Check out https://github.com/mrworf/plexupdate for latest version
# and also what's new.
