rrr-server - watch a tree and continuously update indexfiles
rrr-server [options] principalfile
Prints a brief message and exits.
After you have setup a tree watch it with inotify and keep it uptodate. Depends on inotify which probably only exists on linux.
It is not declared as prerequisites of the F:R:M:Recent package because server side handling is optional. XXX Todo: make server side handling a separate package so we can declare Inotify2 as prereq.
