SVK::Command::Propget - Display a property on path

 propget PROPNAME [DEPOTPATH | PATH...]

 -R [--recursive]       : descend recursively
 -r [--revision] REV    : act on revision REV instead of the head revision
 --revprop              : operate on a revision property (use with -r)
 --strict               : do not print an extra newline at the end of the
                          property values; when there are multiple paths
                          involved, do not prefix path names before values
