Hebrew calendar software creators: can you notify this list when updating the calendar?

[Tomer Cohen]

Sounds that people are aware of this issue. See the following snippet from
'man calendar' -

     calendar.judaic       Jewish holidays (should be updated yearly by the
local system administrator so that roving holidays are set correctly for the
                           current year)

We already have hcal for Hebrew dates instead of cal. Someone should create
hcalendar in addition of calendar. Sounds to me as an easy task for someone
who is familiar enough with Hebrew dates.
