Combined slul command:

for invoking:
* the compilation/build command
* the package manager
* the doc genarator (outputs: html, txt, man-page, etc.)


Compilation:
    slul         = slul build in current directory
    slul build   = build module
    slul clean   = remove outputs
    [maybe] slul install = (build if needed and) install current module
                   * installation of data directories, manpages, license text, etc?
                   * installation of .desktop files / start menu shortcuts?
                   * installation of whatever is needed on MacOS? build and install .dmg file?
                   * library / slul interface installation
                   * call "make install" if there is a Makefile?
   slul test     = run tests
   slul deps     = install build- and runtime dependencies (impl+iface)
   slul build-deps = install build dependencies only

Package manager:
(disallow running as root, unless --system is given?)
(have a --prefix option. it should work with add,remove,update,status,show)
    slul add     = installs a package + iface dependencies + impl dependencies
    slul add --iface-only = installs a package interface + iface dependencies
    slul remove  = removes a package
    slul upgrade = updates a package, or all if none is specified
    slul search  = searches for a package
    slul status  = shows installation status and version
    slul show    = show package information + dependencies + status
    slul repo add PKG-PATTERN|all URL
    slul repo remove [PKG-PATTERN|all] URL      (all removes *all* entries, not just the "all" entry)
    slul notarize = signed reproducible build/test upload:
                    Uploads src&bin hashes + test result +
                    compiler impl/version + backend&version +
                    arch name + distro name/pkg-version (if customized) +
                    signature of the contents above

Package maintenance:
    slul pkgman init
    slul pkgman push
    slul pkgman reviewed
    slul pkgman api-reviewed
