# scripts fail.

# The following environment variables must
# be set:
# $TFB_REPOPARENT   parent folder of the repository
# $TFB_REPONAME     name of the repository folder
# $TFB_REPOURI      URI for the git repository
# $TFB_MAILINGLIST  email address for the mailing list
# $TFB_LOGSFOLDER   location to transfer logged output
