+=head2 term_width
+
+Try to guess terminal width to use with formatting of debug output
+
+All you need to get this work, is:
+
+1) Install Term::Size::Any, or
+
+2) Export $COLUMNS from your shell. 
+
+(Warning to bash users: 'echo $COLUMNS' may be showing you the bash
+variable, not $ENV{COLUMNS}. 'export COLUMNS=$COLUMNS' and you should see 
+that 'env' now lists COLUMNS.)
+
+As last resort, default value of 80 chars will be used.
