# This has the common functionality for tbprerun/tbrun/tbend.

# tbs_initdbi(dbname) - Initializes a DBI connection to the testbed database
#                       Returns the database handle.
# tbs_prefix(s) - Returns the file prefix.  I.e. strips off \..+$ from the end.
# tbs_out(s) - Spits s out to stdout and LOGFILE.
# tbs_exec(s) - Acts like system except STDOUT and STDERR are both spat out
#               through tbs_out.  Returns 1 on failure and 0 on success.
