+# reorder and reformat a file in columns
+#
+# this utility takes lines from its standard input and reproduces them,
+# partially reordered and reformatted, on its standard output.
+#
+# It has the same effect as a 'sort | column -t', with the exception
+# that empty lines, as well as lines which start with a '#' sign, are
+# not affected, i.e. they keep their position and formatting, and act
+# as separators, i.e. the parts before and after them are each sorted
+# separately (but overall field widths are computed across the whole
+# input).
+#
+# Options:
+#   -i:
+#   --ignore-case:
+#	Do not consider case when sorting.
+#   -d:
+#   --default:
+#	What to chage empty fields to.
+#    -s <N>:
+#    --split=<N>:
+#       Treat only the first N whitespace sequences as separators.
+#       line content after the Nth separator will count as only one
+#       field even if it contains whitespace.
+#       Example : '-s 2' causes input 'a b c d e' to be split into
+#       three fields, 'a', 'b', and 'c d e'.
+#
+# boards.cfg requires -ids 6.
