# File: install_from_archive.yml
# These plays download and install an application distributed as an
# archive. Set the appropriate variables as follows:
#
# Required variables:
# -------- ---------
#
# key: The application's key. This value will determine the
# name of the directory (in /opt) where the application
# is finally installed.
#
# title: The application's formal name.
#
# version: This value indicates what version should be downloaded
# and is generally set in the "versions.yml" file and
# copied within the task's vars file.
#
# url: The URL where the application's installation archive can
# be downloaded.
#
# Optional variables:
# -------- ---------
#
# checksum: The URL of the file containing a checksum for the archive
# which will be downloaded by this playbook.
#
# archive_path: If the archive includes a path prefix for each file, This
# value allows the archive to be "relocated" to a directory
# named by the version. If this variable is empty, the
# archive path is assumed to be ".".
#
# desktop_file: If the application has a GUI, this variable should point
# to a template that will be completed and copied to
# /usr/share/applications. If this variable is empty,
# no templating is performed.
#
# executables: A list of the executables that should have symlinks placed
# into /usr/bin. If this variable is empty, no symlinks
# are created.
