# If changing this file please take care to try to make your changes as
# portable as possible.  That means at a minimum only use POSIX supported
# features and functions.  However, it may be desirable to use an even
# more narrow set of features than POSIX, e.g. Solaris /bin/sh only has
# a subset of the POSIX shell features.  If in doubt, limit yourself to
# features already used in the file.  Reviewing the history of changes
# may be useful as well.
