# AllConv installer  —  works on ANY Linux distribution
#
# Installs AllConv so you can run it from anywhere by typing:
#     allconv            (command-line tool)
#     allconv --gui      (graphical interface)
#
# It also adds "AllConv" to your application menu.
#
# This script only relies on things every Linux distro has:
#   - python3 + pip
#   - the freedesktop ~/.local/bin and ~/.local/share directories
# The only distro-specific part (installing Tkinter for the GUI) is
# auto-detected for apt, dnf, yum, pacman, zypper, apk, xbps, eopkg,
# emerge and nix.
#
# Usage:  ./install.sh            (normal install)
#         ./install.sh --with-tk  (also try to install Tkinter via sudo)
