"OpenBSD::PackageName" is the canonical interface to package names
handling.
"OpenBSD::PackageName::url2pkgname($url)"
strip an $url of path elements and ".tgz" suffixes, yield a
canonicalized package name.
"OpenBSD::PackageName::splitname($pkgname)"
split a $pkgname into a $stem, a $version number, and a (possibly
empty) list of @flavors components. If the name contains no
identifiable version, $version will be "undef".
"OpenBSD::PackageName::splitstem($pkgname)"
short version of "splitname" that extracts only the $stem.
"OpenBSD::PackageName::is_stem($string)"
check whether a $string is a valid stem, as opposed to a full package
name. Useful for commands that take either full names or stems, and
need to reconstruct the full name from the stem.
"OpenBSD::PackageName::findstem($stem, @pkgnames)"
look up a $stem into a list of @pkgnames. Return a list of candidates
for further processing.
"OpenBSD::PackageName::compile_stemlist(@pkgnames)"
alternate interface that is faster when lots of look ups are
involved. Compile a list of @pkgnames into an object $h that can be
queried using "$h->findstem($stem)".
