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.
