\h|DESCRIPTION|
\cb{brep-clean} deletes expired package builds from the brep \cb{build}
database. The build is considered expired if the package version is not
in the \cb{package} database, or the configuration is not listed in the
<buildtab> file, or the timestamp is older than the one specified for
this build's toolchain (see \cb{--stale-timeout}).
Note that \cb{brep-clean} expects the \cb{build} and \cb{package} database
schemas to have already been created using \l{brep-migrate(1)}."

explicitly. If unspecified, the default timeout is zero (never expire)."
