Usage:
transpose [-namecol <col-id>]

and vice versa.
The -namecol flag can be used to specify a column
in the input table which will provide the column names for
the output table.
The first column of the output table will contain the
column names of the input table.
Syntax for the <col-id> argument is described in Section 6.2.
