-It is possible to set multiple dependencies separated by space:
+Tasks are by default sequential. A task start date defaults to the end date of the preceding task.
+
+A colon, `:`, separates the task title from its metadata.
+Metadata items are separated by a comma, `,`. Valid tags are `active`, `done`, `crit`, and `milestone`. Tags are optional, but if used, they must be specified first.
+After processing the tags, the remaining metadata items are interpreted as follows:
+
+1.  If a single item is specified, it determines when the task ends. It can either be a specific date/time or a duration. If a duration is specified, it is added to the start date of the task to determine the end date of the task, taking into account any exclusions.
+2.  If two items are specified, the last item is interpreted as in the previous case. The first item can either specify an explicit start date/time (in the format specified by `dateFormat`) or reference another task using `after <otherTaskID> [[otherTaskID2 [otherTaskID3]]...]`. In the latter case, the start date of the task will be set according to the latest end date of any referenced task.
