# Installing Gradint on GNU/Linux systems
# ---------------------------------------

# Gradint does not need to be installed, it can
# just run from the current directory.

# If you do want to make a system-wide installation
# (for example if you want to make a package for a
# GNU/Linux distribution), I suggest running as root
# the commands below.

# For a distribution you might also have to write
# man pages and tidy up the help text etc.

# Depends: python + a sound player (e.g. alsa-utils)
# Recommends: python-tk python-tksnack sox libsox-fmt-all madplay

# ---------------------------------------
