+# todo
+
+# if package specifiers are given as arguments after the package file
+# it will only install those packages.
+
+# package specifiers are of the form pkg[-ver[-rel]], i.e the
+# release can be omitted, and the version-release can be omitted.

+# zpm install -f foo-0.1-1.zpm
+# zpm install -f foo.zpm foo-0.1

+# recording repo: where we record what we've done
+# source: where we get the package and files from
+# install root: really just a prefix, but thought about differently,

+# package name to install, could be "all" or "all most recent"
+# but for now, assume only one package in a file?
