## 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.
