      7 .Sh SYNOPSIS
      8 .Nm
      9 .Sh DESCRIPTION
     10 .Nm
     11 flips the rows and columns of a matrix given by standard input,
     12 effectively transposing it around the diagonal axis.
     13 This means that an input file with N columns and M rows is output
     14 as M columns and N rows.
     15 Input fields must be tab-separated and each line must contain the
     16 same number of fields.
