       Text::Tabs -- expand and unexpand tabs per the unix expand(1) and unexpand(1)


         use Text::Tabs;

         $tabstop = 4;  # default = 8
         @lines_without_tabs = expand(@lines_with_tabs);
         @lines_with_tabs = unexpand(@lines_without_tabs);


       Text::Tabs does about what the unix utilities expand(1) and unexpand(1) do.  Given a line
       with tabs in it, expand will replace the tabs with the appropriate number of spaces.
       Given a line with or without tabs in it, unexpand will add tabs when it can save bytes by
       doing so (just like "unexpand -a").  Invisible compression with plain ASCII!


         # unexpand -a
         use Text::Tabs;

         while (<>) {
           print unexpand $_;

       Instead of the "expand" comand, use:

         perl -MText::Tabs -n -e 'print expand $_'

       Instead of the "unexpand -a" command, use:

         perl -MText::Tabs -n -e 'print unexpand $_'
