# Please note that in the interest of general portability, some common
|
||||
# bourne shell constructs were avoided because they weren't guaranteed to
|
||||
# be available in some earlier implementations. I've tried to make this as
|
||||
# portable as possible.
|
||||
#
|
||||
# Among the more interesting lossages I noticed with some bourne shells
|
||||
# are:
|
||||
# 1) Some don't have an `unset' builtin
|
||||
# 2) In some implementations the `shift' builtin can't take a
|
||||
# numerical argument.
