-- Runtime dependency detection.
-- Incremental package installation.
-- Fast dependency solver.
-- File conflict detection.
-- Package alternatives system.
-- 3-way handshake for /etc/ configuration files.
-- Binary stripping.
-- `shellcheck` compliant.

-- `kiss-fork`: Copy a package's repository files into the current directory.
-- `kiss-link`: Link a repository file to another repository.
-- `kiss-manifest`: Display all files owned by a package.
-- `kiss-maintainer`: Display the package maintainers.
-- `kiss-new`: Create a boilerplate package.
-- `kiss-orphans`: List orphaned packages.
-- `kiss-outdated`: List outdated packages based on Repology versions.
-- `kiss-owns`: Check which package owns a file.
