46 * \brief Implements parsing of CCL qualifier specs in files
51 * $Id: cclqfile.c,v 1.11 2007-04-30 19:55:40 adam Exp $
55 * Revision 1.3 1995/05/16 09:39:26 adam
58 * Revision 1.2 1995/05/11 14:03:56 adam
59 * Changes in the reading of qualifier(s). New function: ccl_qual_fitem.
60 * New variable ccl_case_sensitive, which controls whether reserved
61 * words and field names are case sensitive or not.
63 * Revision 1.1 1995/04/17 09:31:45 adam
64 * Improved handling of qualifiers. Aliases or reserved words.
