# CGI-BIN mode usage
#

# We use the following environment variables from the cgi-bin environment:
#
#       $PATH_INFO                      - action requested
#       $QUERY_STRING           - contains the query
#       $REMOTE_USER            - user account name
#       $REQUEST_METHOD         - request method
#       $SCRIPT_NAME            - script name
#


# We create the following variables as we go along,
# these will both be empty if this is a guest user
#
#       $main::RemoteUser                                       - contains the remote user name
#       $main::UserAccountDirectoryPath         - contains the path name to the user account directory
#       $main::UserSettingsFilePath                     - contains the path name to the user information file
#

#       Function:       bGetDatabaseDescriptions()
#
#       Purpose:        This function reads the database description file and places it in the
#                               hash table global, note that the hash table is not cleared before
#                               we start to add kay/value pairs to it.
#
#                               Any line which starts with a '#' or is empty will be skipped.
#
#                               An error will be generated if we try to redefine a value for a 
#                               key that has already been defined.
#
#                               An error here should be considered fatal.
