## Syntax of the shell scripts. ##
## ----------------------------- ##
# We use `/bin/sh -n script' to check that there are no syntax errors
# in the scripts. Although incredible, there are /bin/sh that go into
# endless loops with `-n', e.g., SunOS's:
#
# $ uname -a
# SunOS ondine 4.1.3 2 sun4m unknown
# $ cat endless.sh
# while false
# do
# :
# done
# exit 0
# $ time sh endless.sh
# sh endless.sh 0,02s user 0,03s system 78% cpu 0,064 total
# $ time sh -nx endless.sh
# ^Csh -nx endless.sh 3,67s user 0,03s system 63% cpu 5,868 total
#
# So before using `/bin/sh -n' to check our scripts, we first check
# that `/bin/sh -n' is not broken to death.
