RELEASE/1.1RELEASE/1.2debug-cidebug-ci-sanitisersstereowalls-data
Last change on this file since e0c7cd1 was e0c7cd1, checked in by Olly Betts <olly@…>, 18 years ago

cavern: Add validity checking for dates in *date commands with feature
test. A date entered as just "year" or "year.month" now becomes a date
range for the relevant period (previously it became a single date near
the middle of that period).
