HerbTracker

-- ============================================================
-- Herb Tracker for LegendMUD (Mudlet)

-- Tallies herbs carried by your character: loose items flagged
-- "herb", and stacked herb bundles (type "BUNDLE", using bundle.count).
-- Also opens any CONTAINER items (bags) to catch herbs stored inside.

-- Recipes for poultices etc. are NOT exposed over GMCP (LegendMUD
-- deliberately excludes them), so this shows raw herb counts only -
-- you'll still need to do the "how many poultices" math yourself,
-- but the counts here should make that quick.
