 Tiny and straightforward package manager for KISS written in POSIX `sh`.
 
-- Only 600~ lines of POSIX `sh` (See [cloc](#cloc)).
+- Less than 1000 lines of POSIX `sh` (excluding blank lines and comments).
 - 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.

 The `contrib` directory contains a set of simple scripts to extend the package manager. These are just simple and stupid automations which parse the package format.
 
-- `kiss-cargo-urlgen`: Generate sources for rust packages.
 - `kiss-chbuild`: Spawn a throwaway chroot.
 - `kiss-chroot`: Enter a KISS `chroot`.
-- `kiss-depends-finder`: Find missing dependencies by parsing 'ldd'.
 - `kiss-depends`: Display a package's dependencies.
 - `kiss-export`: Turn an installed package into a KISS tarball.
 - `kiss-fork`: Copy a package's repository files into the current directory.
 - `kiss-link`: Link a repository file to another repository.
-- `kiss-manifest-tree`: Display all files as tree owned by a package.
 - `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 - `kiss-outdated`: List outdated packages based on Repology versions.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.
-- `kiss-repodepends`: Display a package's original dependencies.
 - `kiss-reset`: Reset the system to the base.
 - `kiss-revdepends`: Display packages which depend on package.
 - `kiss-size`: Show the size on disk for an installed package.
