- * rules.h - targets, rules, and related information
- *
- * This file describes the structures holding the targets, rules, and
- * related information accumulated by interpreting the statements
- * of the jam files.
- *
- * The following are defined:
- *
- * RULE - a generic jam rule, the product of RULE and ACTIONS.
- * ACTIONS - a chain of ACTIONs.
- * ACTION - a RULE instance with targets and sources.
- * SETTINGS - variables to set when executing a TARGET's ACTIONS.
- * TARGETS - a chain of TARGETs.
- * TARGET - an entity (e.g. a file) that can be built.
- *
- * 04/11/94 (seiwald) - Combined deps & headers into deps[2] in TARGET.
- * 04/12/94 (seiwald) - actionlist() now just appends a single action.
- * 06/01/94 (seiwald) - new 'actions existing' does existing sources
- * 12/20/94 (seiwald) - NOTIME renamed NOTFILE.
- * 01/19/95 (seiwald) - split DONTKNOW into CANTFIND/CANTMAKE.
- * 02/02/95 (seiwald) - new LEAVES modifier on targets.
- * 02/14/95 (seiwald) - new NOUPDATE modifier on targets.
