Text::Tabs(3)          Perl Programmers Reference Guide          Text::Tabs(3)

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

         use Text::Tabs;

         $tabstop = 4;
         @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.  Invisible compression with plain ascii!

       expand doesn't handle newlines very quickly -- do not feed it an entire document in one string.  Instead feed
       it an array of lines.
