libtest-tabs-perl 0.005-1 (ppc64el binary) in ubuntu xenial

 Test::Tabs scans your project/distribution for any perl files (scripts,
 modules, etc) for the presence of tabs.
 .
 In particular, it checks that all indentation is done using tabs, not
 spaces; alignment is done via spaces, not tabs; indentation levels
 never jump up (e.g. going from 1 tab indent to 3 tab indent without an
 intervening 2 tab indent); and there is no trailing whitespace on any
 line (though lines may consist entirely of whitespace).
