import "say_hello"  # Import some functions. See functions/say_hello.sh for more info.

# Info (Please declare it, as it will be used outside of this script, too)
# Required info
name=hello  # Name of the software, not the package name.
            # Same source files will be used for the same software, despite the package name being different.
version=2.10

# Optional info
update_url="https://ftp.gnu.org/gnu/$name/"  # URL to a downloadable plain-text file which updates when a new version is available.
update_names="$name-$version.tar.gz"  # Specify what the lines containing the version number look like on the download page.
                                      # It's a comma-separated list, and can contain multiple entries.
                                      # Every entry must contain at least one instance of $version,
                                      #   as another program will look for any different versions on the same page.
                                      # You may not need to set this, in which case the program will try to guess it from the download commands.

vcs_compile=true  # Set this to true if it's a vcs package, and we've just downloaded an update for it. This is meant to be used in functions/header_end hooks, and has to be set before header_end is called (or by a header_end hook).

# Please note that setting the above info from an imported script is supported, as long as it's done in the header.

# Astronaut will generally prefix internal variables with "_". There are, however, a few exceptions.
#   Some of those you can touch, some not.
# "You shouldn't even look, unless you're hacking really bad, but definitely don't touch"-variables:
# - dir_build (You cd into it automatically. Just use relative paths or $PWD.)
# - dir_source (This is handled by the commands detailed below. You should have no use for it.)
# "Look, but don't touch"-variables:
# - dir_install
# - dir_sysroot
# - dir_prefix
# "You'll only make your own life more difficult if you use them wrong, so I don't care what you do"-variables:
#   (Only use these to change the behaviour of some commands over the whole script.)
# - cmd_download
# - cmd_extract
# - vcs_compile
# - options

# Get them files.
