NAME         top

       flatpak-build-sign - Sign an application or runtime

SYNOPSIS         top

       flatpak build-sign [OPTION...] LOCATION ID [BRANCH]

DESCRIPTION         top

       Signs the commit for a specified application or runtime in a local
       repository.  LOCATION is the location of the repository.  ID is
       the name of the application, or runtime if --runtime is specified.
       If BRANCH is not specified, it is assumed to be "master".

       Applications can also be signed during build-export, but it is
       sometimes useful to add additional signatures later.
