Basic assumptions
-----------------
Obviously we assume that there is a configure script, and that after the
ConfigCmd has been run, there is a Makefile.
ConfigCmd: We assume the configure script accepts a --with-hc flag
BuildCmd: We assume the default Makefile target will build everything
InstallCmd: We assume there is an install target and a variable $(prefix)
that can be overridden
(./Setup --install-prefix=foo -> make prefix=foo install)
Note that we assume that this does *not* register the package!
SDistCmd: We assume there is an dist target
RegisterCmd: We assume there is a register target and a variable $(user)
UnregisterCmd: We assume there is an unregister target
