-@command{median} is command line tool for getting the median
-values of groups. For each input line it parses the first
-column, separated by a blank space, as a value and the remainder
-of the line as a key. If the line does not contain a blank
-space and entire line is parsed as a value and the key is an
-empty string. If the line however contains a blank space it is
-included in the key, thus a line contain only a value and a line
-contain a value followed by a blank space is not interpreted has
-having the same key. @command{median} outputs the median value
-for each key. In @command{median}'s current implementation the
-keys will be sorted in the output. Keys do not have to be sorted
-or groups. @command{median} will do its best to print the median
-of in the same format as the input values. The input for a group
-is of even number and is numerical the mean value of the two
-middle values is used, otherwise the lower of the two middle
-values is is used. Of course, if the number of values is odd,
-the middle value is always used and it does not matter whether
-the input is numerical or not.

-Simple example:
-@example
-$ cat <<EOF | median
-> -10
-> 2
-> 4
-> 3
-> 50
-> EOF
-3
-@end example
-
-Example with 3 groups, one non-numerical:
-@example
-$ cat <<EOF | median
-> 10 group 1
-> 20 group 1
-> 01 group 2
-> 02 group 2
-> a group 3
-> b group 3
-> c group 3
-> d group 3
-> EOF
-15 group 1
-01.5 group 2
-b group 3
