b2/: first tentative version of hierarchy parser, with example 2012-04-25 23:14:39 +03:00
b2/: make top-level hierarchy item an action, not just a rule This allows the definition of optional global fields. For now, we (ab)use this for FP (footprint). 2012-04-29 05:30:50 +03:00			`{ FP=* }`
b2/: syntax change: use = for instead of : for format declarations 2012-04-26 00:25:35 +03:00			`T=<comp> {`
