As mentioned, one of the new features in Greenstone v2.81 is the ability
to schedule the automatic rebuilding of a greenstone collection using the
GLI.

Scheduling will require some configuration in order for it to work. The
following link has more information on how to do this for each platform:

> Greenstone Runtime:

> Greenstone now compiles for Linux on 64-bit platforms. All programs are
> compiled natively for 64-bit, except for those that rely on mg/mgpp, which

> FLI - Fedora Librarian Interface
> ---------------------------------
>
> The Fedora Librarian Interface (FLI) is very much like GLI in that it

> (put into) a Fedora repository. The process of building a collection
> using FLI
> exports documents into a repository maintained by a Fedora server rather
> than

> Fedora installed. More information on how to install Fedora and set it up
