dnl The difference between LIBVIRT_ARG_WITH and this macro is that the former

dnl is mostly an enhanced drop-in replacement for AC_ARG_WITH, whereas the

|
dnl latter is tailored for adding an argument that is going to be used to
|
|
dnl switch a feature on and off: as a consequence, it optionally supports
|
|
dnl specifying the minimum version for libraries the feature depends on and
|
|
dnl automatically builds a suitable description from the feature name.
