# A word about this shell script:
|
|
#
|
|
# It must work everywhere, including on systems that lack
|
|
# a /bin/bash, map 'sh' to ksh, ksh97, bash, ash, or zsh,
|
|
# and potentially have either a posix shell or bourne
|
|
# shell living at /bin/sh.
|
|
#
|
|
# See this helpful document on writing portable shell scripts:
|
|
# http://www.gnu.org/s/hello/manual/autoconf/Portable-Shell.html
|
|
#
|
|
# The only shell it won't ever work on is cmd.exe.
