Over the last year there has been discussion of adding -xml, -csv, and
other formatted text data streams. Would that be easier for you to work
Obviously all of the functionality that is being performed by the
various command line tools is in C. libadmin is the library that is
used by the IBM AFS Server Manager on Windows. Any functionality that
is missing could be filed as a feature request to
email@example.com so that it is tracked somewhere.
