-    If you want to supply flags to a regex, then surround it with slashes
-    and append the flag. The following flags are supported:
+    A note on modifiers: the regexp engine used in tablizer uses another
+    modifier syntax:

-        i => case insensitive
-        ! => negative match
+        (?MODIFIER)
+
+    The most important modifiers are:

    Example for a case insensitive search:

-        kubectl get pods -A | tablizer "/account/i"
+        kubectl get pods -A | tablizer "(?i)account"

-    If you use the "!" flag, then the regex match will be negated, that is,
-    if a line in the input matches the given regex, but "!" is supplied,
-    tablizer will NOT include it in the output.
-
-    For example, here we want to get all lines matching "foo" but not "bar":
-
-        cat table | tablizer foo '/bar/!'

-  PUT FIELDS TO CLIPBOARD
-    You can let tablizer put fields to the clipboard using the option "-y".
-    This best fits the use-case when the result of your filtering yields
-    just one row. For example:
-
-        cloudctl cluster ls | tablizer -yid matchbox

-    If "matchbox" matches one cluster, you can immediately use the id of

  ENVIRONMENT VARIABLES
    tablizer supports certain environment variables which use can use to
    influence program behavior. Commandline flags have always precedence
    over environment variables.

 Example for a case insensitive search:

-    kubectl get pods -A | tablizer "/account/i"
