 Tablizer  can   be  used   to  re-format   tabular  output   of  other
 programs. While you  could do this using standard unix  tools, in some
-cases it's a hard job.
+cases it's a hard job. With tablizer you can filter by column[s],
+ignore certain column[s] by regex, name or number. It can output the
+tabular data in a range of formats (see below). There's even an
+interactive filter/selection tool available.

 Usage:

    If the option -v is specified, the filtering is inverted.

+  INTERACTIVE FILTERING
+    You can also use the interactive mode, enabled with "-I" to filter and
+    select rows. This mode is complementary, that is, other filter options
+    are still being respected.
+
+    To enter e filter, hit "/", enter a filter string and finish with
+    "ENTER". Use "SPACE" to select/deselect rows, use "a" to select all
+    (visible) rows.
+
+    Commit your selection with "q". The selected rows are being fed to the
+    requested output mode as usual. Abort with "CTRL-c", in which case the
+    results of the interactive mode are being ignored and all rows are being
+    fed to output.
+
  COLUMNS
    The parameter -c can be used to specify, which columns to display. By
    default tablizer numerizes the header names and these numbers can be
