When Berkeley DB is distributed as part of the GNU system, the Berkeley
DB license requirement that derivative works using Berkeley DB themselves
be freely redistributable, does not apply to programs loading standard
UNIX interfaces via the GNU C library and dynamically loading Berkeley DB
support to obtain the underlying functionality.
As a special exception, when Berkeley DB is distributed along with the
GNU C Library, in any program which uses the GNU C Library in accord
with that library's distribution terms, it is also permitted for
Berkeley DB to be loaded dynamically by the GNU C Library to implement
standard ISO/IEC 9945 (POSIX 1003) and Unix interface functionality.

# Palestine
# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
#
# From 1917 until 1948-05-15, all of Palestine, including the parts now
# known as the Gaza Strip and the West Bank, was under British rule.
# Therefore the rules given for Israel for that period, apply there too...
#
# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
# (except a short occupation by Israel from 1956-11 till 1957-03, but no
# time zone was affected then). It was never formally annexed to Egypt,
# though.
#
# The rest of Palestine was under Jordanian rule at that time, formally
# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
# the country's previous name of "the Hashemite Kingdom of the
# Trans-Jordan"). So the rules for Jordan for that time apply. Major
# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
# East Jerusalem.
#
# Both areas were occupied by Israel in June 1967, but not annexed (except
# for East Jerusalem). They were on Israel time since then; there might
# have been a Military Governor's order about time zones, but I'm not aware
# of any (such orders may have been issued semi-annually whenever summer
# time was in effect, but maybe the legal aspect of time was just neglected).
#
# The Palestinian Authority was established in 1993, and got hold of most
# towns in the West Bank and Gaza by 1995. I know that in order to
# demonstrate...independence, they have been switching to
# summer time and back on a different schedule than Israel's, but I don't
# know when this was started, or what algorithm is used (most likely the
# Jordanian one).
#
# To summarize, the table should probably look something like that:
#
# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
# ------------+-----------+-----------+-----------+-----------
# Israel | Zion | Zion | Zion | Zion
# West bank | Zion | Jordan | Zion | Jordan
# Gaza | Zion | Egypt | Zion | Jordan
#
# I guess more info may be available from the PA's web page (if/when they
# have one).
# From Paul Eggert (1998-02-25):
# Shanks writes that Gaza did not observe DST until 1957, but we'll go
# with Shapir and assume that it observed DST from 1940 through 1947,
# and that it used Jordanian rules starting in 1996.
# We don't yet need a separate entry for the West Bank, since
# the only differences between it and Gaza that we know about
# occurred before our cutoff date of 1970.
# However, as we get more information, we may need to add entries
# for parts of the West Bank as they transitioned from Israel's rules
# to Palestine's rules. If you have more info about this, please
# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
# These rules for Egypt are stolen from the `africa' file.
