Comment(by leif):
P.S.:
{{{
#!sh
#!/this/file/must/be/sourced
flagfile=... # whatever its name / location is
# Set SAGE64 to "ignore" on everything but MacOS X / [Open]Solaris unless
SAGE_PORT is set:
test -z "$SAGE_PORT" &&
case "$UNAME" in
Darwin|SunOS) # Add other operating systems later if appropriate.
# Do nothing here.
;;
*)
export SAGE64=ignore
esac
test -z "$SAGE64" && export SAGE64=no # default to no if not set
case "$SAGE64" in
yes|no)
# Also make sure SAGE_LOCAL is defined if it is used; here or
above.
if [ -f "$flagfile" ]; then
saved64=`cat "$flagfile"`
if [ "$saved64" != "$SAGE64" ]; then
# inconsistent -> error
fi
else
echo $SAGE64 > "$flagfile"
fi
;;
ignore) # do nothing
;;
*)
# invalid value -> error
esac
# And no messages, only errors to stderr
}}}
A bit shorter, isn't it?
