Dockerfile

# CCFE — The Curses Command Front-end — minimal runtime image.
#
# Depends on stock Debian packages ONLY:
#   * perl            (core modules: POSIX, IPC::Open3, Text::Balanced, ...)
#   * libcurses-perl  (the Curses / ncurses + form + menu bindings)
#
# The previous Dockerfiles built a bespoke GCC 7.5 + binutils + statically
# linked ncurses + a 2020 Perl, on the theory that issue #1 ("segfault on
# forms") needed a static Curses.  It did not: the crash was a Perl logic
# bug (building a curses menu from an empty item list), fixed in v1.60.
# See docs/history/REFACTOR.md for the analysis.  This image therefore just installs
# the distro packages and runs the program.
