KISS PACKAGE MANAGER
________________________________________________________________________________
The KISS package manager is a self-contained POSIX shell script which is written
in a highly portable way. It should run anywhere with a POSIX shell and POSIX
compliant core utilities.
The KISS package manager is a small, self-contained POSIX shell script with an
emphasis on portability.

[1] Git is also required for contribution to the distribution itself. Strictly
speaking, nothing forces you to use git. Remote repositories and git based
sources will simply become unusable.
[2] There is no standard utility for the generation of sha256 checksums. While
sha256sum is listed above, the package manager also supports sha256, shasum,
digest and openssl as fallbacks.

[4] These three compression methods are required as pretty much every package
source uses them as the tarball compression method.
[4] The first three compression methods are required as 99% of package sources
use them as the tarball compression method. Nothing as of yet uses zstd in
the official repositories.
The other compression methods are optional as no package sources (in the
official repositories) make use of them.
[5] A privilege escalation utility is only needed when installing packages to
a directory owned by another user (user -> root) or (root -> user).
[5] A privilege escalation utility is only needed when using the package
manager as a normal user for system-wide package installation.
Installation to a user-writable directory does not require root access.
Root usage of the package manager (chroot usage for example) does not
require these utilities.
[6] If these are missing, binary stripping and/or the dependency fixer will
simply be disabled.
Regarding 'strip'; It has a POSIX specification, though the spec doesn't
contain any arguments whatsoever.
This makes our usage of 'strip' non-POSIX. That being said, our usage is
compatible with most 'strip' implementations (binutils, elfutils,
elftoolchain, llvm, etc).

[3.0] Configuration
________________________________________________________________________________
The package manager has no configuration files and no changes need to be made to
The package manager has no configuration file and no changes need to be made to
the system prior to its use. While there is no configuration file, this does not
mean that there is no possibility for configuration.
The package manager can be configured via the use of environment variables. I
believe this to be the best configuration method for the problem at hand.
Environment variables can be set system-wide, per-user, conditionally, for a
single invocation and so on.
