+**What it does**
+
+With this tool you can specify (by naming the header) which columns need to be leftmost.
+The columns which are not specified will be ordered as before, right of the columns which were specified.
+
+Input file::
+
+    AHeader BHeader CHeader DHeader
+    a       b       c       d
+    a       b       c       d
+
+Specifying **CHeader** and **BHeader**, as the columns that should be leftmost, generates::
+
+    CHeader BHeader AHeader DHeader
+    c       b       a       d
+    c       b       a       d
