# sc: openser control; tool for maintaining openser's databases
#
# History:
# --------
# 2005-03-25 - SC with DBText support (cesc santasusana)
# 2005-07-08 - Removed all non-DBText functions (daniel)
# 2006-05-16 - added ability to specify MD5 from a configuration file
#              FreeBSD does not have the md5sum function (norm)

           * Database Selection *
 
 The exact location of the dbtext files to use must be set. Export
 DBTEXT_PATH="/path/to/dbtext" (no trailing slash). No password is needed
 for dbtext. All these parameters can also be set in the "serctl" script
 file directly. Note that dbtext tries to mimic the results of a MySQL DB,
 but it is not always possible to reproduce them 100%.
 DBText files field order is the same as in the MySQL database.
