You mean like this?

    flags sql.make-SQL-file CAL_CONFIG <cal-config> ;
          ^^^^^^^^^^^^^^^^^
    . . .

    generators.register-standard sql.make-SQL-file : CONFIG_SRC : SQL ;
                                 ^^^^^^^^^^^^^^^^^

Thank you! I was thinking the generator ID was 'make-SQL-file' and the 
'sql' was a module ID that could be omitted in the scope of the sql 
module. I now see the error of my ways. ;-)

For the benefit of the list, this mistake isn't as daft as it sounds. 
The Boost Build docs use the following example:

import generators ;
generators.register-standard verbatim.inline-file : VERBATIM : CPP ;
actions inline-file
{
    "./inline-file.py" $(<) $(>)
}

And the text says, "By convention, generators use the same name of the 
action block as their own id."
