DESCRIPTION="Midnight Commander fork with dynamically loaded panel plugins"
HOMEPAGE="https://blue-panels.github.io/mc6/ https://github.com/blue-panels/mc6"
# Use the bootstrapped release asset (configure and mc-version.h), not GitHub's
# generated archive; its bytes do not change with archive regeneration.

# Spell check is compiled into the internal editor.
REQUIRED_USE="spell? ( edit )"
RESTRICT="!test? ( test )"

# libarchive backs arcmc, the only remaining archive VFS. libmagic and zlib use
# unconditional header probes in core code, so gating them would be automagic.
