Tiny and straightforward package manager for KISS written in POSIX `sh`.
- Less than 1000 lines of POSIX `sh` (excluding blank lines and comments).
- Highly portable (will run in any POSIX compliant environment).
- Runtime dependency detection.
- Incremental package installation.
- Fast dependency solver.

## Dependencies / Portability
```sh
# - Anything with a specification should follow it (POSIX, BSD, etc).
# - Anything without a specification which has ONLY a single (widely used)
# implementation will be considered portable (git, curl, etc).
#
# POSIX utilities
# - sh (POSIX)
# - find (POSIX) -type f, -type d, -exec {} [+;], -o, -print, !
# - ls (POSIX) -l, -d
# - sed (POSIX) -n, s/<search>/<replace>/g, /<delete>/d
# - grep (POSIX) -l, -F, -x, -f, -q, -v
# - sort (POSIX) -r, -u, -k
# - tee (POSIX) -a
# - date (POSIX)
# - mkdir (POSIX) -p
# - rm (POSIX) -f, -r
# - rmdir (POSIX)
# - cp (POSIX) -f, -P, -p, -L, -R
# - mv (POSIX) -f
# - chown (POSIX) -h
# - diff (POSIX) -U
#
# Misc
# - su* (sudo, doas, su) (in order, optional)
# - git (downloads from git) (must link to curl)
# - curl (downloads over http) (also needed by git)
# - sha256 (multiple fallbacks: sha256sum, shasum, sha256, openssl, etc)
#
# Compiler/libc utilities (depends cc & libc)
# - readelf (optional) (Part of compiler toolchain) (GNU, LLVM or elfutils)
# - strip (optional) (Part of compiler toolchain) (GNU, LLVM or elfutils)
# - ldd (optional) (Part of libc)
#
# Tarball compression
# - tar (as portable as can be) (merely: cf, tf, xf)
# - bzip2 (widely used) -d, -z
# - xz (widely used) -d, -z, -c, -T
# - gzip (widely used) -d, -6
# - zstd (optional) -d, -z, -c
# - unzip (optional)
# - lzma (optional)
# - lzip (optional)
