   \cb{brep-load --help}\n

   \c{\b{brep-load} [<options>] <loadtab>}

   \h|DESCRIPTION|

   \cb{brep-load} reads the list of repositories from the specified
   <loadtab> configuration file, fetches their manifest files, and loads the
   repository and package information into the \cb{package} database, suitable
   for consumption by the \cb{brep} web module.

   Note that \cb{brep-load} expects the \cb{package} database schema to have
   already been created using \l{brep-migrate(1)}.

   Also note that \cb{brep-load} requires \l{bpkg(1)} to fetch repository
   information. See \cb{--bpkg} for more information on the package manager
   program."
