rsbuild [options] package.dsc

  Uploads a Debian source package to a remote host and builds it using sbuild.
  The following options are supported:

   --arch="arch"         Specify the Debian architecture(s) to build for.
   --dist="dist"         Specify the Debian distribution(s) to build for.
   --buildd="host"       Specify the remote host to build on.
   --buildd-user="name"  Specify the remote user to build as.

  The current default configuration is:

   BUILDD_HOST = $BUILDD_HOST
   BUILDD_USER = $BUILDD_USER
   BUILDD_ARCH = $BUILDD_ARCH
   BUILDD_DIST = $BUILDD_DIST

  The expected remote paths are:

  BUILDD_DIR  = $BUILDD_DIR
  
  sbuild must be configured on the build host.  You must have ssh
  access to the build host as BUILDD_USER if that is set, else as the
  user executing cowpoke or a user specified in your ssh config for
  '$BUILDD_HOST'.  That user must be able to execute sbuild.
