# Statically compile nnn with netbsd-curses and musl libc on Ubuntu
#
# netbsd-curses: https://github.com/sabotage-linux/netbsd-curses
# musl libc: https://www.musl-libc.org/
#
# Notes:
#   - Run the script within the top-level nnn directory
#   - installs musl and downloads netbsd-curses library
#
# Tested on Ubuntu 20.04 x86_64
